no sound HDA-intel AD1984

[Elias K Gardner]

This is a new problem that occured over the last few days in intrepid today being the 24th oct 08. My sound is usually muted so I cannot narrow it down more. I have no sound whatsoever. Built in speaker is fine I have sound in XP.

I ran an also script I ran an automatic sound information collection scrip found at https://wiki.ubuntu.com/DebuggingSoundProblems the info can be found here http://www.alsa-project.org/db/?f=fec33adab69327b84e10ec8ba472c384db7661fa

Problem solved due to post #9 on http://ubuntuforums.org/showthread.php?t=942529&highlight=sound

Here is the issue. PCM volume was set to 0 in alsamixer, however, running alsamixer as recommended in the terminal only brings up the the master volume. If you instead run 'alsamixer -Dhw' in a terminal it brings up the master volume plus all the others. Here it is now possible to see that PCM was muted and set it higher.

So the bug here is that PCM volume was inexplicably muted on some intrepid update.

I am also unsure as to why -Dhw is now required when the alsamixer command alone used to suffice.

I can file a new bug about this if it is helpful let me know. For now I will mark the package as alsa if that is wrong please correct me.

After the recent pulseaudio update, my snd_hda_intel sound also stopped working -- just a low crackling sound.

I tried the alsamixer -Dhw trick, and sure enough, PCM volume was at 0. I turned PCM volume up to max and now my sound plays normally again.

However, I think the PCM volume 0 is just one symptom of the problem. When I shutdown or restart my computer, it always hangs during the "Shutting down ALSA...." process. So, my sound is working now, but there is still a problem related to ALSA and/or pulseaudio.

Erik,

thank you SO MUCH ! I've been struggling fr days with this !

I can't believe that was so stupid !

There are LOTS of duplicate bugs, why no one says something ?

My bug was certainly a duplicate of this one and I'm going to signal that.

Thanks again
Bye

It's confirmed. The simptom is there and I could remove it thanks to the Erik's indication.

Why is PCM volume set to 0 and is there anything happening to prevent pulseaudio from doing so with an update? Any information needed? Thanks!

[cato (catonano)]

I'm not sure I understand the question.

   1. I don't know why the PCM volume is set to 0
   2. I guess there must be something that prevents pulseaudio from doing
   so, but I'm not able to help, I was hoping some developer could know better
   than me.
   3. Why do you ask wether any information is needed ? Are you asking to me
   ? I don't need any further information ? Anyone else needs further
   information ?

Also I don't understand clearly who you are: are you a developer and are you
asking for more info ? Or are you a user and trying to help with this bug ?

Thanks
Bye
Cato

Sorry for the confusion (I did not want to speak to you directly):
I am a normal user and want to help. I asked in general if anyone needs more information because I want to help.
On my computer PCM was set to 0 after a pulseaudio update, so I just wanted to know if anyone is working on this at the moment, so that this problem gets fixed.
