Re: sound card does not work after upgrading to Oneiric.

I have a similar issue.

Sound hardware being HDA Intel Realtek ALC262. Phonon does not show this in the Audio Hardware Setup, it only shows Internal Audio. Alsamixer does detect the sound hardware. PulseAudio volume control does not show the HDA Intel hardware.

The most similar issue to the poster I have is audio 'disappearing' (including mic) after a few days of uptime (and being logged in).

I had no such problems with 11.04. This is a clean install of 11.10.

Just putting this out there

Re: sound card does not work after upgrading to Oneiric.

Can you run dmesg just after sounds starts getting quirky? Just to see if there is some pci conflict.

Maybe in your BIOS setup you can disable one of the audio devices. Or you can choose to blacklist one of the drivers. But let's start with the dmesg bit.

ok... I knew this moment will come
my microphone went dead again...
as xinixs asked me, this is the dmesg i got (dmseg | grep Audio only gave me this line):
[ 20.261074] input: HD-Audio Generic HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input9

my microphone is dead, and I can see this msg with the word "input", which im sure related to the issue, but i cant understand it, any ideas...?

Re: sound card does not work after upgrading to Oneiric.

I keep believing it is a PCI conflict between the two sound chips. We can try to disable the HDMI audio driver.

Can you post the output of

lsmod | grep -i "snd"

please?

Re: sound card does not work after upgrading to Oneiric.

OK, let's try the blacklisting thing. Open console and do the followiing:

sudo nano /etc/modprobe.d/blacklist.conf

At the end of the file, add

blacklist snd_hda_codec_hdmi

Close with Ctrl-o (that is a letter o, not a zero)

reboot. You can run

lsmod | grep -i "snd"

to see if the blacklisting has worked

Good luck!

Re: sound card does not work after upgrading to Oneiric.

ok... i did those, (except i used vim instead of nano since im much more familiar with it)
now this is what i get from lsmod and still my microphone does not work:

Re: sound card does not work after upgrading to Oneiric.

Well, there may be two things going on:
1. The mic volume needs to be set properly. Have you tried alsamixer in the console?
2. Instead of the hdmi driver, you need to blacklist the snd_hda_intel driver.

Looking again at the driver list, it might happen that blacklisting the intel driver renders you completely soundless, so in that case blacklisting is not the way to go.

Sorry this is such a pain for you. In the end, if things just don't work, you might want to fall back on 11.04....

ok, I checked alsamixer everything was fine, but simply by clicking the mixer from taskbar found out capturing devices was muted (i dont know when and how that happened!!?!!!) and its abit of surprise to me to see alsamixer and the GUI taskbar mixer show different status (should'nt they be sync?)
anyways... now its working, but as I really want to understand whats happening for future reference (i hope that day doesnt come!) tried blacklisting each againg. with blacklisting the intel my whole sounds totally went dead, but blacklisting hdmi leaves both in & out sounds fine.
im having a hard time to understand whats happening, the intel sound card is the onboard one, right? isnt it better for hdmi to be working so my onboard drives wouldnt get so occupied...?

Re: sound card does not work after upgrading to Oneiric.

should I manually install any drivers...?

[Xinixs]

Re: sound card does not work after upgrading to Oneiric.

I am glad it's working. What I did was sort of make an educated guess. Seeing that the hdmi device was indicated as the one causing trouble in KDE, I thought you might need to blacklist it. I am no expert, but I believe the hdmi driver makes use of the same physical sound chip, but directs the sound to the hdmi port.

The intel driver is the one to bring the sound chip to life, hence disabling it leaves your system muted. At the moment, you will not have any sound if you connect an hdmi device, but I suppose you can live with that.

There is a bug there which you have now worked around, but of course, it is not the best solution.

There is afaik no need for manually loading drivers.

alright thanks
I really hope this would be the end of this topic and I hope it helps others...

Re: sound card does not work after upgrading to Oneiric [SOLVED]

You can expect the sound to be muted again whenever there are updates to the alsa or phonon or pulseaudio packages -- apparently that is the new default.

Re: sound card does not work after upgrading to Oneiric [SOLVED]

I have a very similar problem and think this blacklist technique could fix it for me as well, not sure what to type, can anyone help....
