After one of the last updates the Sound is lost.

**tirant** · February 15th, 2012

Standard Ubuntu 11.10 64 bits (Xeon Quad Core)
Creative Sound Blaster CA0106 card.(Sound Blaster Audigy SE iirc)

It has been in the last days, when I totally lost my audio. I checked everything in sound-settings and alsamixer. Switched users and tried all my old kernels. Sound is not coming back.

It seems it has also happened to other people, and the common hardware is 64bit + CA0106 Sound Card:

http://linux.ittoolbox.com/groups/te...64-bit-4645160

Booting my installation UBUNTU 11.10 Usb stick brings sound back, the same when booting on Windows 7 (64bit).

I am a developer, but have no idea about sound problems (working in embedded systems), and I do not have much time to debug this, so I ask for your help.

Ubuntu also detects another Audio Card on my nvidia GT520 (HDMI connection). I cannot try that, as I dont have any HDMI device available.

Well after following both guides, sound is still not working.

If you haven't remove the 3.0.0-15 kernel, then boot into that until it gets fixed (I've already seen multiple Launchpad bug reports about this hardware/kernel combination).

I have already booted into all the old kernels i have installed. Nothing. Nada

But thanks for the reply.

I am having the same issue

The system seems to see the Soundblaster, but alsamixer only shows the HDMI sound device and I'm not using HDMI for anything. The Soundblaster modules are loaded:

Update:

Looking at /proc/asound/modules, I see only the hda_intel which I don't want, and the ca106 is missing:

Code:

ws04:~$ cat /proc/asound/modules
 0 snd_hda_intel

Interestingly, another similar workstation has sound working and has:

Code:

ws05:~$ cat /proc/asound/modules
 0 snd_hda_intel
 1 snd_ca0106

Where would I look to find out why the module seems to be running from lsmod, but it's not showing up in /proc/asound/modules? It seems like this might lead to the solution. Any help much appreciated.

**geoffree** · February 29th, 2012

Maybe this will Help: When I was trying to adjust the Pulse Audio Volume panel, I saw that the playback was activating the Input indicator bar. Perhaps the circuits got wired backwards. Im using natural language because I dont know what is actually happening except for the visual error.

So it is obvious that there is a problem with the audio on 11.10.
Are there any workarounds? Any fixes? From my experimenting with repair it appears that the playback mode is going through the input channels.
I am able to hear audio from news programs or other media. It's that I can't use my microphone to make calls or record any input from the mic.
So...
