Public bug reported:
My motherboard is a gigabyte z77mx-d3h, apparently using intel
pantherpoint audio. I don't have all the details with me at the moment
and can add more information to this report when I get home.
Symptoms:
ubuntu 12.04 - out of the box:
* clicking the volume control app from the ubuntu system settings causes the
system settings window to freeze. The sound control panel never appears and
there isn't any way to list or choose output devices.
* playing any audio (such as in rhythmbox, movie player, etc) causes that
application to freeze.
I've had a look at not seen any particular errors in the logs of these
applications. if the experts here could point me to the right places to
find the information I would be happy to post it.
Workaround:
I worked around the problem by uninstalling pulseaudio and falling back
to alsa-mixer. The Ubuntu hda intel sound howto was no help.
This allows me to use the motherboard audio (i use spdif output), as
well as USB audio without issues in most applications. For example I can
play music in rhythmbox, watch movies, and use youtube - all with sound.
Despite the workaound, Wine still displays the original symptoms. For
example if alsa is set as sound driver, the audio settings tab in wine
settings freezes.
Thanks All!
