no sound after upgrading to 8.10

[Kymus]

After upgrading to Ibex, everything was fine at first... ran things for a few hours, audio was fine.

Go to bed, turn the system off, turn it back on the next morning and of course the magic computer goblin paid my box a visit because I am not getting any audio at all.

When I first booted, I noticed that the sound was automatically muted, so I changed that, and I've of course fiddled with the volume and that produced no results.

I'm using the onboard sound from my motherboard (Foxconn NF4UK8AA), which the Sound Preferences says is NVidia CK804 with ALC850 NVidia CK804.

I've fiddled with every option under sound playback and every test has thus far produced no results.

I was browsing through the Ubuntu forum and found this suggestion:

Code:

sudo killall pulseaudio

sudo alsa force-reload

Quote:
and then go to System>Preferences>Sound and change everything to ALSA

Unfortunately, this produced no results

Another suggestion I received was to check to make sure Ubuntu is recognizing my sound card; it seems that it is recognizing it fine:

Code:
kymus@Shouxing:~$ sudo lshw -C multimedia
  *-multimedia
       description: Multimedia audio controller
       product: CK804 AC'97 Audio Controller
       vendor: nVidia Corporation
       physical id: f
       bus info: pci@0000:00:04.0
       version: a2
       width: 32 bits
       clock: 66MHz
       capabilities: pm bus_master cap_list
       configuration: driver=Intel ICH latency=0 maxlatency=5 mingnt=2 module=snd_intel8x0

I tried upgrading alsa and... yeah, nadda.

I have followed the basic troubleshooting for debugging sound problems (https://wiki.ubuntu.com/DebuggingSoundProblems) and unfortunately, that didn't help either.

I've run the "Automatic Sound Information Collection" and this is the url it spit out:

Do you still have that problem?
In your "Automatic Sound Information Collection" it says that PCM volume is set to 0, please turn up your PCM volume slider.

[Kymus (x-kymus-x)]

Hi Cruncher, thank you for responding.

I last used Ubuntu about a month or more ago (lack of sound for nearly 6 months finally got to me). I figured that the last and final hope was that an upgrade to 9.04 would magically work things out.

I will boot over to Ubuntu probably tomorrow and I will report (hopefully good) results.

I assume that by the PCM slider you mean the volume bar?

[Cruncher (ubuntu-wkresse)]

If you click on the speaker in the panel, a window should open with many volume controls. If it doesn't, launch "gnome-volume-control" from a terminal.
Master, PCM, *and* Wave have to be *all* on, otherwise you won't be able to hear sound (try settings of around 70%, and make sure all 3 channels are unmuted of course. I get distortions if I set PCM to 100%, so always use less than that).
If you do not see at least three (double-)sliders labelled Master, PCM, and Wave, please tell me which ones you see.

And if you don't get responses after a few days from bugs you posted, you can always try to post a question ( https://answers.launchpad.net/ubuntu ), or open a thread in the community forum ( http://ubuntuforums.org/ ) instead.

[Kymus (x-kymus-x)]

Ok, I opened the Volume Control.

Master was already at 100%
PCM was muted and at 0%; I unmuted and cranked it up to 100%

I do not see Wav (and I checked under preferences as well; it's not there either)

I see:
Master (100%, unmuted)
PCM (100%, unmuted)
Surround (100%, unmuted)
Center (100%, unmuted)
Line-in
CD
Microphone
PC Speaker

Still not a bit of sound, unfortunately

[Kymus (x-kymus-x)]

It goes without saying, of course, that I made sure that my speakers were on and the volume was up (I started it at no sound and gradually turned it up to max)

[Cruncher (ubuntu-wkresse)]

I just checked and in my case it's named "Wave", but I guess you don't have that either, then?
Which could be part of the problem. But I don't know enough about the sometimes crypting linux sound configuration to have more suggestions for you, sorry.

[Kymus (x-kymus-x)]

Thanks anyway :)

My last resort will be to try and upgrade to 9.04 in a few weeks or so. Sometimes upgrading magically fixes things (or breaks things, in my case :D).

Hi Kymus,

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 324879

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.

Hello Jeremy,

This issue is solved. For whatever reason, I opened a new thread here (https://answers.launchpad.net/ubuntu/+question/71573) after discovering that sound was working in Kubuntu, but not in Ubuntu. Thank you for checking up on this problem; the problem has been solved.
