Comment 6 for bug 587388

So let me get this correct... you are recommending that a standard user install packages from:
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa
"Crack of the Day" builds of alsa-driver code.
to troubleshoot this issue? Sorry, but I've been there & done that months ago (see:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/477154?comments=all
and
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/573284
(start around comment #9)
and please see:

I'm already using linux-backports-modules-alsa in order to get the speaker/headphone jack working properly. I'll not install ppa:ubuntu-audio-dev/ppa (I just had to do an in-place reinstall to get the partition that I'd tested this on previously back to working condition). I suggest that you take the existing information provided and work on the issue. I can provide an updated alsa-info.txt if needed, and sincerely appreciate the offer to assist, the but to suggest that I install a daily/dev/ppa series of packages to troubleshoot the issue isn't viable IMO.

Note that the CX20582's also still have this issue as well. Again, thanks for having a look - if you can help sort this out a *lot* of folks will be very happy.
