Comment 23 for bug 1195377

I have a similar issue with Dell Inspiron 1090 (Duo). I am not sure if this is exactly the same bug, but the built-in speaker just stops working after a while (usually a few seconds after system startup or wakeup) and remains silent until the next reboot or suspend/wakeup. The headphone jack remains functioning though. When I plug the headphones in and out, the sound volume and speaker mute settings change accordingly in alsamixer, which I presume shows that the two states are correctly detected by alsa, however, nothing is heard from the built-in speaker when the headphone is unplugged. Sound test in Ubuntu sound settings aslo confirms this.

The issue started after an upgrade in ubuntu 12.10 and now I have upgraded to ubuntu 13.10 but the problem is still there.

Will this get fixed for Inpiron Duo as well? Should I start a new bug report thread?
