I am currently testing Natty Alpha 1 and this issue still persists. The
fix is to compile ALSA from source with the patch as described in the
original submission.
** Description changed:
Feel free to mark this as a dupe of 278648, but as of Karmic, ThinkPad
R61s with Conexant CX20549 (Venice) sound devices have non-functioning
microphones and less-than-stellar sound output. This submission is in
hopes that ALSA can be patched by the Lucid LTS to include a working mic
and fully functional sound.
Currently the workaround requires the following:
1. Grabbing the ALSA upgrade script from
http://ubuntuforums.org/showthread.php?p=6589810
2. Downloading the Conexant patch from
https://bugtrack.alsa-project.org/alsa-bug/login.php?username=guest&password=guest&return=/alsa-bug/view.php%3Fid%3D4163
3. Applying the patch:
$ cd /to/your/directory/where/the/script/is/saved
$ sudo sh ./AlsaUpgrade-1.0.x-rev-1.17.sh -d
$ sudo patch
/usr/src/Alsa-1.0.20/alsa-driver-1.0.20/alsa-kernel/pci/hda/patch_conexant.c
~/path/to/patch_conexant.c.patch
$ sudo ./AlsaUpgrade-1.0.x-rev-1.17.sh -i
4. Saving the patch and script in case of future kernel upgrades (at
minimum performing the last command in step 3 after a kernel upgrade).
5. Upon rebooting, readjusting sound levels and performing the general
PA fixes as suggested by other Ubuntu forum threads.
According to the comments in 278648, this has NOT been submitted upstream and
there doesn't seem to be a consensus on how to best notify upstream of the
patch. This is a potential showstopper for those with R61i machines who need
to be able to use the microphone and the sooner this patch can be applied
before Lucid, the better.
