Title:
No audio under X (only when booted to text mode) - MS-7549, Realtek
ALC888, Green Line Out, Rear Pulseaudio fails to detect card
Status in “pulseaudio” package in Ubuntu:
Confirmed
Bug description:
When booting in graphics mode, direct to Unity, sound seems to work
fine.
When booting in text mode, sound works at the console level; apps like
mpg123 play properly with either pulseaudio or alsa drivers. However,
after starting X, apps (mpg123, xine, totem, etc.) do not report
errors and appear to be operating properly, but also do not generate
any audio. Looking at the Sound panel in gnome-control-center, no
devices are listed under the "Hardware" tab and only "Dummy Output"
under the "Output" tab (in contrast to the 4 audio outputs listed when
booting in graphics mode).
In some cases, the app trying to do audio starts thrashing the CPU (or
it may be X thrashing it on the app's behalf), and Ctrl-Alt-F2 to a
text console and killing the app is the only way to make the system
usable again.
The audio behavior is the same whether I start X with Unity or a
traditional window manager like WindowMaker.
I have tried steps 1-7 under
https://help.ubuntu.com/community/SoundTroubleshooting without
success. Since I'm getting sound at console level, it's clearly not a
matter of the drivers not being present at all and the "Manual
Installation" step seems inapplicable.
