Public bug reported:
Hi. I installed Ubuntu 12.04 version. In subsequent kernel updates, the
sound began to fail. When playing on the internal speakers of the
Toshiba L745 with Conexant CX20585 card, the sound is played for 25
seconds to 1 minute, and then silence. Sound indicator bar indicates
that continuous playing. If I connect the headphones, sounds perfectly.
The rest of the components, internal microphone and external HD Sound
run smoothly. The problem persists in 12.10 and 13.04.
System:
Ubuntu 12.10
Alsa-base:
1.0.25+dfsg-0ubuntu3.1
PulseAudio:
1:2.1-0ubuntu4
Module Alsa DKMS installed but not working.
