View Full Version : [ubuntu] sound suddently stopped in 9.04

The sound had been working just fine on my Ubuntu 9.04 (AMD 64). However, it suddenly stopped making any sounds - even when logging on. The speaker volume is up, and I have tried to get sound from any sources with no luck.

Any ideas?

What is the last thing you did before this issue happen?

have you checked alsamixer? (in a terminal)

The last thing I did before the sound went was reading my e-mail, and opened up a youtube video. Video was fine, but the sound was not there. Got checking then, and found I had no sound.

BTW, I have a dual boot machine with Windows - sound is fine in Windows, so presume that addresses hardware issues.

Hmmm - I am pretty much of a Newbie here. I did go to System/Preferences/Sound. I found that the Sound Events, Music and Movies, and Audio Conferencing (Sound Playback) were all set on Autodetect which is what I believe they were set on when the sound was working. I tried a few other settings, but no other setting would produce a test sound either, so I put them back on Autodetect.

I had also searched the Internet for possible solutions, and added a suggested line of code to the bottom of the Alsa file, but no change.

What sound chip are you running?

In terminal:


lspci | grep Audio

Post the output please.

totally off-topic, but relevant nevertheless...

for what it's worth...

email address harvesters are going wild here...

your mileage may vary...

I just had the same thing happen.

Sound was working fine last night. Noticed sound didn't work a little bit ago and tried a reboot. Still same issue....No sound! REALLY weird!

I'll let you know if I find the issue on mine.

-edit-

OK, found my issue. This is dang strange, as I had made absolutely NO CHANGES at all.
I checked my alsamixer settings (all was correct)
Checked my sound settings under System>Preferences (changed my default mixer to the correct setting, changed all other options from AutoDetect to PulseAudio; then made sure my mixer was also set correctly in volume properties and checked "ALL" other mixer options for any that were Muted).

Sounds is back! I wish I knew what happened to change it. The ONLY thing I had done before I lost sound, is sudo aptitude update and sudo aptitude upgrade. WEIRD!!!

I entered the lspci | grep Audio command in the terminal, and nothing happened. Just went back to the command prompt.

That's odd. Maybe it's not picking up the sound chip for some reason..

Try pasting the output of:


lspci

and

This happened to both of my Jaunty computers yesterday. I fixed it by hitting the "test" button under sound preferences. For whatever reason that made sound work on flash videos. Strange it happened to both my computers about an hour apart.

Well there it is, and it has been picked up along with a module loaded. Are you certain all your mixer levels are turned up and output isn't muted as suggested earlier in this thread? Another thing to check would be your cabling to the speakers or stereo depending how you have it hooked up.

Other than that not too sure. You can confirm the pulse audio daemon is running with this command:


ps -A | grep pulse

Well there it is, and it has been picked up along with a module loaded. Are you certain all your mixer levels are turned up and output isn't muted as suggested earlier in this thread? Another thing to check would be your cabling to the speakers or stereo depending how you have it hooked up.

Other than that not too sure. You can confirm the pulse audio daemon is running with this command:


ps -A | grep pulse
Been out of town - unfortunately the sound did not fix itself in my absence:)

Here is what I get when I checked pulse audio:

gordonsmall@gordonsmall-desktop:~$ ps -A | grep pulse
3181 ? 00:00:01 pulseaudio
gordonsmall@gordonsmall-desktop:~$


The question mark looks interesting - does this tell you anything about where to look next?

There's a few things you can try.

1) from a terminal, run alsamixer
and make sure that nothing it muted.
2) Check your sound settings under System>Preferences
and just for the heck of it, do like mxboy15u and press "Test" to see if you hear any sound. If you still don't, verify that the correct Mixer is set and maybe change the options from "Auto Detect" to "Pulse Audio"
3) Open the Volume Applet (in the system tray), select the correct device and make sure nothing is muted there either. On mine, Just to be safe (when this issue popped up for me a while back) I selected each one of the devices and made sure that NONE of them were muted. ;-)

This fixed it for me.. I'm not sure how it happened, but 'apparently' the configuration changed after an update and a few of the devices were muted on mine. At least that's what the issue was on mine when this occurred. Your configuration (from what I see) looks fine, so hopefully this 'might' help you get sound back.

Shortly after the last post I restored the audio by the process I have copied below. Everything has been fine until yesterday, and the sound disappeared again. I am confident that this is being done by a certain updates. However, I don't know which updates would be the likely villian, and I also can't find a way to identify or find all the recent updates.I would like to try to be able to remove recent updates until the sound comes back.Can this be done?

Here is the process that worked last time - but not this time.

Getting the ALSA drivers from a *fresh* kernel

Sometimes, sound might be configured correctly, but for some reason or another (tinkering) it stops working. One way to go back to the old setup is to reinstall Ubuntu. However, this step is actually quite unnecessary since you are reinstalling everything because of one thing.

A faster way, is to just remove the problematic packages and reinstall them cleanly.

(1) Remove these packages
Code:

sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils


(2) Reinstall those same packages
Code:

sudo apt-get install linux-sound-base alsa-base alsa-utils

[list]
VERY IMPORTANT NOTE: Ubuntu (GNOME) users have reported that packages 'gdm' and 'ubuntu-desktop' are removed after removing the linux-sound-base packages. If this happens, then do the following
Code:

sudo apt-get install gdm ubuntu-desktop


(3) Reboot

VERY IMPORTANT NOTE: Xubuntu (XFCE) users have reported that packages 'gdm' and 'xubuntu-desktop' are removed after removing the linux-sound-base packages. If this happens, then do the following
Code:

sudo apt-get install gdm xubuntu-desktop


(3) Reboot
Now you may ask "I already had the packages, so why did I go through the trouble of removing them, then installing them". The answer lies in the --purge option which removes all the extra information that accumulated from tinkering and upgrading. After doing a purge then install, the packages are unpackaged as if it they are brand new.
(4) At this point, try using
Code:

aplay -l

you should get your soundcard listed.

* Success - Your soundcard is detected. Go onto the Using alsamixer section, then try playing something on your music or media player.
* Failure - Your card was not detected. You should try compiling your driver, so go onto ALSA drive Compilation.

Some days ago, my sound stopped too.

I followed above instructions (reinstall Alsa) with no succes. If i enter aplay -l, i see my card listed (as DAC, 2nd DAC and PCI). Everything is on, nothing muted (also not with CLI > alsamixer).

What could be wrong? :confused:

What kind of sound should you hear when you play test? Selecting DAC on the analog boxes gives a loud annoying beep and poor sound on MP3's

ps -A | grep pulse =>

3552 ? 00:00:02 pulseaudio

Also an ?. Like Gordon said before: a clue?
