pulseaudio -vv output
This is what I got. Sorry about all the noise regarding an external USB disk I
had plugged in.
Restarting pulseaudio doesn't fix it. Somehow logging out and back in does.
It seems to be a deeper problem than just audio. The external USB disk wasn't
re-mounted after wake up, and even unplugging it and plugging it back in
produced no actions. Shall we blame it on hal, dbus, or what?
Blame Hal, I think.
I have this problem when waking up from resume. My solution is
sudo /etc/init.d/haldaemon restart
And voila, 90% of the time, my problem is fixed. This is not an idea situation,
though! I miss having audio that worked :'(
I'd also bet on hal.
You can be sure by looking at output of following:
$ getfacl /dev/snd/pcmC0D0c
If you don't see yourself there, please close this as duplicate of bug #384271
Also, try switching virtual consoles and look if it made hal change the ACLs
After hibernating once and coming back, my sound was gone, and I also didn't
appear in the in the results of getfacl /dev/snd/pcmC0D0c anymore. Following
bug #314411, which asks the following questions, I have the following answers:
1. Is hald running upon resume? (lshal will tell you)
2. Do you get the permissions back when switching to VT1 and then back? (e.g.
3. Does manually fixing up the ACL's make sound work? Just wondering if it's a
low-level driver problem.
Don't know how :)
4. What ALSA driver are you using?
I'm not sure how to find this out. system-config-soundcard reports the
following information, though:
Model: SB450 HDA Audio, module: snd-hda-intel
I don't think that's what you want, though :)
So, I think it's the same issues as in bug #384271, because I disappear from the
ACLs after hibernating/suspend, and that is restored when switching VTs.
Thanks for peeking in on this :D
