No sound following upgrade to 9.0.4 here, too. PulseAudio Volume Control shows system thinks it's playing sound.

Alsa debugging info here: http://www.alsa-project.org/db/?f=2fe42dc572fff9e05357dc5a48adfa250ee81d07

(turlinux - you may wish to capture some alsa debugging info as well, instructions are here: https://wiki.ubuntu.com/DebuggingSoundProblems)

[Victoria Wilson (mail-vwilson)]

I've now worked through the instructions here too: http://ubuntuforums.org/showthread.php?t=205449

Have recompiled my Alsa drivers successfully but "sudo modprobe snd-" still returns no results:

$ sudo modprobe snd-
FATAL: Module snd_ not found.

[Craig73 (funrun73)]

Do you get any sound at all? I get the drum sounds at the login screen, and crackly sound playing the login music, and then no more sound after that. The only way I can get sound is to set my playback devices to OSS and that only partially works. So Alsa is failing on my system.

This error stands out to me as it is on my system as well

E: alsa-util.c: Error opening PCM device hw:0: Device or resource busy

[Craig73 (funrun73)]

OK - so I created a second account on my system, and logged into it, and problems gone [not just sound problems, but flash videos play properly, my browser doesn't hang, I'm able to play 3d games/2d games and not have X or my computer hang]

So try creating a new (second) account (perhaps called "test") and log into it and see if your problems go away. By that point perhaps I what the issue with my profile is...

[Victoria Wilson (mail-vwilson)]

I get no sound at all (have tried creating another account). Suspect you may have a different problem... check your existing users are groups of the three pulse audio user groups under user administration.

[Craig73 (funrun73)]

(yes - mine was different / solved by removing .pulse and .pulse-cookies and likely related to a system wide equalizer.)

[Victoria Wilson (mail-vwilson)]

This bug would benefit from some input from someone in the Ubuntu sound team, as it appears (from discussion on the Alsa mantis tracker) that Alsa is installed in non-standard locations in Ubuntu. Therefore ubuntu-specific knowledge is required to investigate further!

[Victoria Wilson (mail-vwilson)]

Please could someone with Ubuntu/Alsa specific knowledge take a look at the Mantis thread? It appears Ubuntu uses non-standard configuration for Alsa, so Ubuntu-specific knowledge will be required to resolve this problem.

[Victoria Wilson (mail-vwilson)]

Having put my faith in Ubuntu, and upgraded to the new version at the end of April, I've now been left with pretty much no audio for the best part of six weeks. It's meant I'm unable to use the internet telephony I rely on to stay in touch with relatives and friends in my home country, and has seriously impacted my ability to use my laptop for it's primary purpose since I am a language professional.

The bug was reported to the Alsa team on May first, and "support" was forthcoming until it was shown that the problem was not my misconfiguration but a genuine problem with the drivers, as revealed by their own tools (HDA-analyzer, which - coincidentally - I even had to amend from the faulty script they provide on their website in order to use). Since identifying some technical features of the problem that may actually give us the information needed for a fix, nobody on the Alsa team has responded.

There has been extremely little support from the Ubuntu team, as can be seen from this bug report.

If this were a new install of Ubuntu, I would expect these kinds of problems - but for a standard upgrade to wipe out functionality that was previously working fine really should raise serious questions about how code is managed on this project.

Perhaps someone can explain what is going on to restore this functionality... or perhaps I should start looking again at other distributions.

[Victoria Wilson (mail-vwilson)]

This now appears to have been mostly resolved following a recent update... although headphone detection/playback is only working on one speaker (the one that I managed to get sound through before).

Still, it's great to have the speakers and microphone back in action, as well as one headphone socket, and to not have to use a python diagnostic tool to manually enable sound every time I reboot the laptop :)

[Jeremy Foshee (jeremyfoshee)]

Hi turlinux,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid.

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 368427

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
