Public bug reported:
After upgrading to Ibex, everything was fine at first... ran things for
a few hours, audio was fine.
Go to bed, turn the system off, turn it back on the next morning and of
course the magic computer goblin paid my box a visit because I am not
getting any audio at all.
When I first booted, I noticed that the sound was automatically muted,
so I changed that, and I've of course fiddled with the volume and that
produced no results.
I'm using the onboard sound from my motherboard (Foxconn NF4UK8AA),
which the Sound Preferences says is NVidia CK804 with ALC850 NVidia
CK804.
I've fiddled with every option under sound playback and every test has
thus far produced no results.
I was browsing through the Ubuntu forum and found this suggestion:
Code:
sudo killall pulseaudio
sudo alsa force-reload
Quote:
and then go to System>Preferences>Sound and change everything to ALSA
Unfortunately, this produced no results
Another suggestion I received was to check to make sure Ubuntu is
recognizing my sound card; it seems that it is recognizing it fine:
Code:
ky...@shouxing:~$ sudo lshw -C multimedia
*-multimedia
description: Multimedia audio controller
product: CK804 AC'97 Audio Controller
vendor: nVidia Corporation
physical id: f
bus info: p...@0000:00:04.0
version: a2
width: 32 bits
clock: 66MHz
capabilities: pm bus_master cap_list
configuration: driver=Intel ICH latency=0 maxlatency=5 mingnt=2
module=snd_intel8x0
I tried upgrading alsa and... yeah, nadda.
I have followed the basic troubleshooting for debugging sound problems
(https://wiki.ubuntu.com/DebuggingSoundProblems) and unfortunately, that
didn't help either.
I've run the "Automatic Sound Information Collection" and this is the url it
spit out:
