I have sound, then it goes away by itself.

SpawnHappyJake · 2012-06-14 00:04:57

Hello everybody!

I am transitioning to ArchBang (have a broken Linux Mint 12 on internal and "getting to know" Archbang, which I have actually installed to my external), and have some troubleshooting to do.

After learning to do "aplay -l" and then make the appropriate ~/.asoundrc file (and not forgetting the dot, lol), I was able to get sound for the first time. Mr. Green pointed me off to the wiki, which has the "aplay -l" and ~/.asoundrc tips.

When I boot up and play a song (techniqually it's a video, an *flv video) it usually has sound. If not, it's because the ordering of my sound cards changed. I just tweak ~/.asoundrc and I'm good again.

But eventually the sound just stops. I check to see if the order of my sound cards changed again by doing an "aplay -l". I remember one time that they had, and in that one situation tweaking ~/.asoundrc fixed it. But usually my ~/.asoundrc and "aplay -l" output match, even after it stops.

Obviously the card is unmuted in alsamixer, or else it would have not worked to begin with.

Another funny thing, that I'm curious if is related, is that I've never been able to start volumeicon. I do "volumeicon -b" in terminal and get:

volumeicon: alsa_backend.c:88: asound_get_volume: Assertion `m_elem != ((void *)0)' failed.
Aborted

My user is a member of the audio group.

Today I installed vlc ("sudo pacman -S vlc" didn't work, and it occured to me to try "sudo packer -S vlc", which did work) and ran it from terminal.

I got a message about it not able to connect to pulseaudio, but it played sound anyways. This was before the sound stopped. Then the sound stopped after a while. After closing and opening vlc, it still complained that it could not connect to pulseaudio, and this time did not make sound.

I tryed changing a vlc setting from "Default" to "ALSA audio output". Still no sound. Also tried "Pulseaudio audio output". Also tried oss, which complained that it couldn't open /dev/dsp, which doesn't exist.

I am using USB speakers (which really means I am using a USB external sound card). I tried unplugging and replugging them. Still no sound.

Restarting does temporarily "fix" the issue, but eventually it will go away again.

I noticed the wiki said:

to make most programs use Alsa, make sure /etc/libao.conf only contains the following.

default_driver=alsa10

I have no /etc/libao.conf file. Do I need one?

I do not have an /etc/asound.conf file, so that is not conflicting with my ~/.asoundrc file.

Here is my "aplay -l" output:

When my sound is out, doing "speaker-test -c 2" does nothing.

When I do "sudo ps ax|grep pulse" while there is no sound I just get:
[number] pts/0 S+ 0:00 grep pulse

When I do "sudo lsof | grep snd" while there is no sound, I get absolutely nothing.

My /etc/rc.conf contains "alsa" in daemons:

DAEMONS=(dbus networkmanager !network !dhcdbd syslog-ng @alsa)

I just made a /etc/libao.conf with:
default_driver=alsa10

I will now restart and see how long the sound lasts.

I thought Qemu was the culprit, but the sound has stopped without me ever running it that boot.
Could FireFox be the culprit?

When the sound ceases, FireFox, MPlayer, and VLC all can't make sound. So it is not application specific.

Any ideas?

Cheers,
Jake

Do not forget <code> tags they do make posts a little easier to read

Thanks Mr. Green. I have just rebooted with my new /etc/libao.conf.

I have volumeicon in my tray now. Sometimes I get that, and sometimes I don't.

I had to tweak ~/.asoundrc because my sound cards re-ordered. I still had no sound until I slid the volume needle of volumeicon.

No, it wasn't too low for me to hear. It was almost full-blast before I touched it. Just me touching it woke it up or something.

Testing to see if this lasts.

SpawnHappyJake · 2012-06-14 00:25:07

Nope. Only got one playing of one song. Then it quit.

oliver · 2012-06-14 06:16:40

Can you run this command on three separate occasions:

$ sudo lsof /dev/snd

First run should be on a fresh boot
Second should be when it's working
Third when it's not working

You might have to install lsof (but it's a great app that everyone should have anyway)

SpawnHappyJake · 2012-06-14 09:04:36

Took out /etc/libao.conf because it wasn't doing anything for me, and restarted.

"sudo lsof /dev/snd" never gave me any output. But "sudo ls /dev/snd" did.

My output of "sudo ls /dev/snd" never changed.

Fresh boot:

[shjake@archbang ~]$ sudo lsof /dev/snd
[shjake@archbang ~]$ sudo ls /dev/snd

Note: didn't have volumeicon in my tray this boot.

While it's playing music:

[shjake@archbang ~]$ sudo ls /dev/snd
by-id controlC0 controlC2 hwC2D1 pcmC1D0p pcmC2D0p pcmC2D1p timer
by-path controlC1 hwC0D0 pcmC0D3p pcmC2D0c pcmC2D1c seq

(sudo lsof /dev/snd still no output)

After it stopped making sound:

[shjake@archbang ~]$ sudo ls /dev/snd

by-path controlC1 hwC0D0 pcmC0D3p pcmC2D0c pcmC2D1c seq

$ sudo lsof | grep /dev/snd

SpawnHappyJake · 2012-06-14 16:33:06

When started up:

[shjake@archbang ~]$ sudo lsof | grep /dev/snd
[shjake@archbang ~]$ cat ./.asoundrc

Then I fired up vlc:

[shjake@archbang ~]$ vlc

Vlc is making audible music, dispite the pulse audio error.

It's weird that sometimes I get a volumeicon on boot and sometimes I don't. Perhaps a funtion of whether or not the cards re-order?

The cards re-ordered in the boot I'm in now, and I got a volumeicon in the tray,

Cheers,

oliver · 2012-06-15 06:49:40

TBH, I have no idea how pulse works and I have no idea why it would work and then stop - it makes no sense to me (which isn't really saying too much) but my wild guess would be pulse is the problem.

You can also play around with /usr/share/alsa/alsa.conf

SpawnHappyJake · 2012-06-15 17:34:25

Well, I know that Pulse Audio can cause programs "in" Wine to not have sound, and that doing a "sudo killall pulseaudio" can bring sound back "in" Wine. Haven't tried that command yet. Maybe I should. The thing is, I already looked for processes running pulse and didn't find any, so I didn't think that command would help.

Do you know how to restart the Alsa daemon?

Cheers,
Jake

oliver · 2012-06-15 18:19:26

there is no alsa daemon.. you have to unload and load the modules

SpawnHappyJake · 2012-06-17 13:07:40

According to /etc/rc.conf, there is an alsa daemon. See the last line:

#
# /etc/rc.conf - Main Configuration for Arch Linux

LOCALE="en_US.UTF-8"
DAEMON_LOCALE="no"
HARDWARECLOCK="localtime"
TIMEZONE="America/Montreal"
KEYMAP="us"
CONSOLEFONT=
CONSOLEMAP=
USECOLOR="yes"

MODULES=()

UDEV_TIMEOUT=30
USEDMRAID="no"
USEBTRFS="no"
USELVM="no"

HOSTNAME="archbang"

DAEMONS=(dbus networkmanager !network !dhcdbd syslog-ng @alsa)

Honestly, not having sound is a show-stopper for me. I like to listen to music while doing stuff and also would like to play a game every now and then in Wine. I would really love for this to be solved.

I tried "sudo killall pulse" as well as "sudo killall pulseaudio", both said "no process found". Neither command brought sound back.

Thanks for working with me,
Jake

oliver · 2012-06-17 18:47:09

all the alsa entry in the DAEMONS array does is reset your volume back to the default level.

I don't know - it may be time to remove ALSA and try OSS

Have you tried eliminating all the references to pulse in the asound.conf files?

# Use PulseAudio by default
#pcm.!default {
#  type pulse
#  fallback "sysdefault"
#  hint {
#    show on
#    description "Default ALSA Output (currently PulseAudio Sound Server)"
#  }
#}

#ctl.!default {
#  type pulse
#  fallback "sysdefault"
#}

I would probably do this in the the /etc/asound.conf file in case root needs to start something

SpawnHappyJake · 2012-06-17 18:56:45

That might be the way to go. I think Wine only uses OSS anyways. What would the consequences of switching to OSS be?

What commands do I need to type, and what config files do I need to tweak?

Would it be as simple as "sudo pacman -R alsa" and "sudo pacman -S oss"?

Would VLC still work? I guess it wouldn't be the end of the world if I tried, because I could put it back if that works less.

Cheers,
Jake

oliver · 2012-06-17 19:14:38

I'd probably try the asound stuff first... but if you want to test, try the following (it's untested but there's probably a wiki article on the arch site)

OSS used to be the default choice in linux until it changed to a proprietary license and ALSA took over... but OSS has since switched back to GPL. So it wasn't a *technical* reason that caused the mass migration (but maybe OSS is now behind ALSA in features? I don't really know... you *may* have issues since you have a USB device but it's a simple switch)

1) Install OSS

# pacman -S oss

2) Add oss to the DAEMONS array in /etc/rc.conf (and remove the alsa line)
3) Blacklist the ALSA module

# echo "blacklist soundcore" > /etc/modprobe.d/alsa.conf

4) Reboot
5) Test

$ osstest

SpawnHappyJake · 2012-06-17 19:24:24

Shouldn't "blacklist soundcore" go in /etc/modprobe.d/modprobe.conf?

oliver · 2012-06-17 19:27:26

SpawnHappyJake wrote:

pretty sure you can use either... any file ending in .conf will be read. There may be ramifications in using modprobe.conf that I'm unaware of so feel free to use that. If you boot up and soundcore is not loaded, you're good ($ lsmod | grep soundcore)

SpawnHappyJake · 2012-06-17 19:42:25

I tried "blacklist soundcore" in /etc/modprobe.d/modprobe.conf and _not_ in /etc/modprobe.d/alsa.conf, and when I booted back in,
when I tried to run osstest, I got:

/dev/mixer: No such file or directory

I then put "blacklist soundcore" in /etc/modprobe.d/alsa.conf (so now it's in both config files), rebooted, and got the same thing.

On both occations, "sudo lsmod | grep soundcore" showed that soundcore was running.

So soundcore isn't being stopped by two blacklistings.

Jake

SpawnHappyJake · 2012-06-17 19:43:59

And VLC is playing music somehow. I'll see for how long.

Cheers,
Jake

SpawnHappyJake · 2012-06-19 18:03:42

Nope. Stops working after a while.
Also, I booted up today and the sound cards rearranged. No volumeicon. Maybe whether the volumeicon shows up or not is a function of whether or not the sound cards rearrange.

Cheers,
Jake

SpawnHappyJake · 2012-06-20 23:26:01

Still can't have sound permently. Sometimes it lasts a long time and cuts off after letting it sit for hours, and sometimes I don't get much music-time out of it. Once I only got one song out of it.

I'm amazed that soundcore is invincible the way it is. I have it blacklisted in two differet config files, and it still gets loaded.
On top of that, if I do "sudo modprobe -R soundcore" and then "sudo lsmod", soundcore still shows up. Even if I drop to a root shell and do "modprobe -R soundcore" and then an "lsmod", soundcore shows up.

In fact, I couldn't get any sound modules to unload.

Does anyone know how to remove alsa? I tried "sudo pacman -R alsa", and that didn't work.

After my sound stopped working, I tried to unload and reload the following:
snd_pcm_oss
snd_mixer_oss
snd_usb_audio
soundcore

Still no sound.

Any ideas?
Jake

oliver · 2012-06-21 06:53:07

The ALSA modules are owned by the kernel so the only true way to totally remove it is to run a custom kernel. But blacklisting *should* work. I blacklist a number of modules myself and have never had an issue.

Maybe disabled all the entries in the DAEMONS array and see if it still gets loaded... my *guess* is that some app is not only forcing the load but taking over sound.

What do you have in your autostart file? Any odd IM clients or SIP phones that could be trying to take audio over?

SpawnHappyJake · 2012-06-21 12:47:18

I did not put anything in any startup stuff, however, if by default there is stuff in startup, then there would be.

In light of that, I looked at the "Autostarting" Arch Wiki to see if I can find where these startup files are.

/etc/rc.local looks suspicious, because it has lines that say "amixer". amixer is the mixer for alsa.

Here is this suspicious /etc/rc.local file:

#!/bin/bash
#
# /etc/rc.local: Local multi-user startup script.
#

mkdir -p /var/lib/pacman/sync
cd /var/lib/pacman/sync
touch core.db extra.db community.db

amixer sset 'Master' 90% unmute &> /dev/null

amixer sset 'Surround' 90% unmute &> /dev/null
amixer sset 'Speaker' 90% unmute &> /dev/null
amixer sset 'Headphone' 90% unmute &> /dev/null

Here is my /etc/rc.conf:

#
# /etc/rc.conf - Main Configuration for Arch Linux

Nothing suspicious in /etc/rc.conf (to my novice eyes)

But I noticed that in the /etc/rc.d folder there is a bach script titled "alsa":

I'll try nutralizing alsa in /etc/rc.local and /etc/rc.d/alsa and /etc/conf.d/alsa.

Any other suggestions?

Cheers,

oliver · 2012-06-21 13:06:47

I think the entries in /etc/rc.local *and* having alsa as a daemon on rc.conf are redundant but thats not your issue.

Is it correct to say that sound *always* works on a clean bootup but it will fail at a random time afterwards?

If so, I think there has to be another app taking control.

When I meant startup, I was referring to your (presumably) OpenBox autostart file

What about if you avoid VLC and use something like deadbeef... same issue?

SpawnHappyJake · 2012-06-21 13:06:55

Ok, I tried the idea I had last post, and now I have no sound period.

About my earlier post of trying to remove and reload modules...it's supposed to be a lowercase "r", to remove, not an uppercase "R".

After all that, soundcore still shows up under "lsmod". Doing "sudo modprobe -r soundcore" gives "FATAL: Module soundcore is in use."
Even if I add "-f" for "force".

No oss modules were loaded this time, even though I still have oss under "DAEMONS" in /etc/rc.conf. I did "sudo modprobe snd_pcm_oss" and that seemed to load them all.

But still no sound.

Jake

SpawnHappyJake · 2012-06-21 13:09:51

Whoa! simultaneous posting! Mindwave harmonics, bro!

Yes, I always have sound on startup (until my latest "brilliant" idea ruined it), and then a random time later, it goes away.

It's not application specific. Before I was using MPlayer. It affects MPlayer, VLC, and even listening to YouTube in FireFox.

Let me look at that startup file you mention
Jake

SpawnHappyJake · 2012-06-21 13:11:01

Here is my OpenBox autostart:

(sleep 3 && /usr/bin/nm-applet --sm-disable) &
tint2 &
conky -q &
volumeicon -b &
nitrogen --restore &
#xcompmgr &
#xbacklight -set 100 &
#/usr/bin/synclient TouchpadOff=1 &
#batti &
#fbxkb &

I never touched it
Jake

SpawnHappyJake · 2012-06-21 13:12:06

Oh. volumeicon uses ALSA. Could that be the issue?

SpawnHappyJake · 2012-06-21 13:19:48

I just commented out volumeicon, rebooted, and have sound. Let's see how long that lasts.

I am using VLC. No oss modules are loaded, yet when I switch VLC from "default" to "oss", it still makes sound.
How is this possible? The startup scrolling text did say "starting oss", but without modules?

Soundcore is still loaded.

When I switch VLC to OSS, it says it is using /dev/dsp.

Jake

SpawnHappyJake · 2012-06-21 13:22:48

/dev/dsp does not exist. Yet VLC says it is using it. /dev/dsp is created by snd_pcm_oss according to here: https://bbs.archlinux.org/viewtopic.php?id=99234

snd_pcm_oss is not loaded.

I must still be using ALSA.
Jake

oliver · 2012-06-21 13:32:28

You could try booting to runlevel3 (i.e. no Xorg) and playing an mp3 via mpg123 or something... of course if it's random, who knows how long you have to wait, but until this thing is narrowed down you're kind of stuck

SpawnHappyJake · 2012-06-21 13:35:38

Ok. I'll give that a shot.

oliver · 2012-06-21 13:45:28

might be worth either sticking or twisting with regards to OSS too.

Either get back to ALSA and forget about OSS for a while (and, of course, strip it out) or determine why ALSA is still being run while trying to get OSS functional.

I would definitely get rid of volumeicon too even if it is temporary. There are tons of alternatives and you can use alsamixer until you're ready to test one

SpawnHappyJake · 2012-06-21 14:01:32

Hmm. Well, I booted into runlevel 3 (typing this via iPhone) and told mpg123 to repeatedly play Hank Williams' "Hey Good Lookin'". (first mp3 I could find, the songs (really videos) I was playing before were *.flv files)

Used "--loop -1" to make an infinite loop. Anythig less than zero does that with mpg123.

I'm going to go for a run now. I'll see if it's still going when I come back.

Last time I went for a run to see if it would be stopped by the time I got back, it was still going. (about an hour) Then after using the computer for a good while, sound stopped (mind you this is the same boot from when it was playing music that whole time while I was running). I wonder if I have to be using the computer for it to stop.

Normally, it doesn't last anywhere near an hour.

Well, while that's cranking away, have you checked out my script yet?:

I did... I'll comment there instead though to keep things sane

SpawnHappyJake · 2012-06-21 18:24:17

When I came back (must have been at least 2 hours), Hank Williams was still singing.

So I starting trying to simulate "using my computer" to see if user input would throw it off.
I stopped mpg123 and started playing songs with vlc (works from commandline).

In another tty I dropped to a root shell and went to /sys/class/scsi_host/host0/device/target:0:0:0/0:0:0:0

And ran cat on some of the files.

Also, I ran ls on several directories, and used cd.

I also mounted my external hard drive and started playing music off that.

I ran cat on ~/.asoundrc and ran aplay -l. They match.

So all that to see how it would handle while being used by a user. As opposed to having 0 user input while I'm out on a run.

So far I haven't been able to get the sound to cease, except for when I'm not having it play a song, of course. That's part of the test too. Seeing how it handles being stopped and then being told to play another song.

Maybe you're on to something Oliver!

Cheers,
Jake

Yep. Sound hasn't broken itself in runlevel 3. I think it's official.
The "bug" doesn't happen in runlevel 3, at least I haven't been able to get it to happen.

No OSS modules are loaded, and soundcore shows up under lsmod.

Other than getting OSS off and putting the ALSA stuff back, what are the next steps?

Where do I look for programs that seem to at random get started, assuming the problem is due to a program messing ALSA up that doesn't get ran in runlevel 3?

Do I look in /etc/inittab? What places do you recommend?

Cheers,
Jake

SpawnHappyJake · 2012-06-21 20:50:50

Hmm. Now I didn't get any sound on boot-up (switched back to runlevel 5), even though my aplay -l and ~/.asoundrc match. Of course, channels are loud enough and unmuted in alsamixer.

When I uninstalled OSS, it said that it put the ALSA modules back in place. I was hoping that'd fix it.

Rebooting.

SpawnHappyJake · 2012-06-21 20:59:57

Ok, I removed both blacklistings of soundcore (which didn't do anything because soundcore loads anyways, even in runlevel 3, assumably because it's in the kernel image itself?).

Then I rebooted. The soundcards reordered, so I had to edit ~/.asoundrc. After that, I got sound. I'll see for how long.

SpawnHappyJake · 2012-06-22 00:39:53

Ok guys, this might be a breakthrough!

Unfortunately, my sound still stops eventually, but I found out that if I tell it to use my PCI sound card and I plug my earbuds in that, I get sound through that sound card.

So maybe it's only usb audio functionality that has an issue.

I tried unloading snd_usb_audio and reloading it, but that didn't fix it.

My earbuds' cable is too short to get to me from that card (my usb speakers have a thing with a long cable on it that sits on my desk that I can put earbuds into), and I want to use my USB speakers anyways because they're those magic Bose speakers that create surround sound with only two physical speakers. You tell your system that it's a 5.1 card. And the sound quality is really good. My other speaker set (not usb speakers) seem to have become possesed (sometimes they decide what volume they want to be, crakle, and don't make as good sound quality). So simply using the other sound card is not a satisfactory solution.

Any other ideas?

Cheers,
Jake

oliver · 2012-06-22 07:37:37

did you try disabling volume-icon?

SpawnHappyJake · 2012-06-22 10:37:44

Yes, volumeicon is commented out in the OpenBox autostart thing.

Jake

SpawnHappyJake · 2012-06-22 23:53:53

Ok, another discovery.

Recently I booted up and had no sound because the sound cards re-ordered. I edited ~/.asoundrc to match aplay -l. Still no sound.

I remembered that one time when I had volumeicon in my tray (before I took it out of startup, of course) and the sound wasn't working, by me lowering the volume way down and then back up, the sound came back in Mint.

This actually goes back to an earlier memory in Linux Mint. I couldn't get sound to work, and I reached for my physical volume knob, turned it way up, then brought it back down. On the way up it got shocked back to life. I may have had a similar incedent with the software volume in Mint, but after I jolted it a time or two, the issue never came back.

Turning the physical knob doesn't help my ArchBang situation, but I thought I'd give the software volume slider a shot.

Now that volumeicon is out of the startup, I thought I'd give alsamixer a shot (lower volume way down, then bring it back up).

I tried that with alsamixer once, and the sound still didn't come back.

But this last time, I tried it with alsamixer, and that _did_ make the sound come "back". Though that time I did not have sound from startup, so maybe "back" is a little misleading, but ultimately it is coming back because I lost sound the previous boot.

Thank you for your continued dedication!

SpawnHappyJake · 2012-06-23 16:11:59

Happened again. Booted up, sound cards were re-ordered, edited ~/.asoundrc to match "aplay -l", and still no sound. Lowering volume with alsamixer brought sound back. Then I brought the volume back up, and it was still good.

Notice the actual problem is still there. I might have a temporary fix for it, but it keeps breaking.

SpawnHappyJake · 2012-06-23 16:22:27

My sound just stopped. It stopped after already having done the alsamixer trick, which is what got me sound this boot. I tried the alsamixer trick again, and still no sound. Apparently the trick only works for getting sound the first time if there is no sound on startup, not after it goes away.

SpawnHappyJake · 2012-06-23 16:55:49

Oops. I forgot to replace "oss" with "alsa" in rc.conf. That's why I wasn't having sound on startup. I'll see how it lasts now. I have a feeling it will still cut off after a while, given I'm just back where I was when I started.

Maybe this won't be solved until an snd_usb_audio update, or possibly a kernel update, given ALSA is in the kernel image.

SpawnHappyJake · 2012-06-25 09:56:52

Sorry folks, I'll be unavailable this week. How about picking it up the next? Have a good one!

cirrus · 2012-08-04 08:03:49

i had same same where no soundcard was being recognised i added an alsa-base.conf file similar to http://pastebin.com/314T04RG then devices was found only alsamixer showed soundcard as 2nd device so i edited the file like so .. install sound-slot-0 /sbin/modprobe snd-card-0 to -card-1 & install sound-slot-1 /sbin/modprobe snd-card-1 to card-0 . good luck

SpawnHappyJake · 2012-08-04 15:53:14

Thanks for the effort Cirrus, but that's not my problem. My installation can detect all sound cards just fine. It's just that eventually it stops putting sound out through the USB sound card, but not during runlevel 3 (command line). I have only witnessed the bug when booted into a GUI.
