[Bug 489453] Re: laptop internal speakers not working, however external speaker/headphone works

[Mitch Towner]

1. Please ensure all "linux-backports-modules-alsa-" packages are not installed 
(including "linux-backports-modules-alsa-karmic-generic" that I asked you to try previously).
2. Install the "crack of the day" alsa-driver from 
https://edge.launchpad.net/~ubuntu-audio-dev/+archive/ppa Also ensure that you install the "linux-alsa-driver-modules-2.6.31" package from that same repository.
3. Ensure there are no added model quirks in the file /etc/modprobe.d/alsa-base.conf (there would only be quirks in this file if you have edited it).
4. Do a complete shutdown, as a reboot does not seem to make these settings "stick".
5. Ensure that the correct channels are not muted using alsamixer (from a terminal window).
6. Do a complete shutdown, as a reboot does not seem to make these settings "stick".
If this does not resolve your issue,please run the command apport-collect -p alsa-base 511685 so that I am able to help you further diagnose this issue.
Thanks in advance!
