Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: Medium
       Assignee: Ubuntu Audio Team
         Status: Fix Released

This bug is to track upstream ALSA bugs
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1618 and its duplicate

This bug causes no sound at all at many newer centrino laptops (Acer, for
example), without any errors from ALSA or from apps. It seems to be caused by
incorrect sound-routing in the mixer and is model-specific (some configs with
these chips probably may work). The issue has been brought up in ubuntu forums
several times (notably http://www.ubuntuforums.org/showthread.php?t=76019, but
also http://ubuntuforums.org/showthread.php?t=75979, possibly others). At the
moment, upstream bug is assigned but still open.
