Title:
[ICH4 - Intel 82801DB-ICH4, playback] No sound at all after upgrade to
Raring (13.04)
Status in “alsa-driver” package in Ubuntu:
New
Bug description:
After upgrade from 12.04 LTS to 13.04, I have no sound on my Intel
82801DB-ICH4.
Identical installation running on another machine with another chipset has
sound, so the problem must be specific to the Intel 82801DB-ICH4 chip.
What can I do?
