Title:
[Inspiron 1420, SigmaTel STAC9228, Speaker, Internal] fails after a
while or plug in and out headphones
Status in “alsa-driver” package in Ubuntu:
New
Bug description:
Regression from kernel 3.8.x to 3.9.x alsa drivers. After upgrade to
Ubuntu+1 the internal speakers stop working randomly or when plug in
and unplug headphones.
Distributor ID: Ubuntu
Description: Ubuntu Saucy Salamander (development branch)
Release: 13.10
Codename: saucy
Linux zontar 3.8.0-26-generic #38-Ubuntu SMP Mon Jun 17 21:46:08 UTC 2013

Changing this data[2] setting in hda-analyzer does not appear to have
any effect on kernel 3.10.0-0 running system. Must reboot to restore
sound functioning on speakers.
