[pulseaudio-discuss] alsa module fails after rebooting

[Pete Nesbitt]

Hi,
I have a system serving music locally and over the network. It was
working properly (once I took it off wireless), however after shutting
it down (to move it) the ALSA modules are failing to load.

Maybe this is not a PA issue, it may be an ALSA problem but thought I 
would post anyway.

I am auto loading the alsa modules.

Here is the log information for when it was working, followed by the
same info when it failed. I don't know why it would quit working after 
a reboot.

When it was working:

Now ALSA fails, as does the daemon:

I modified my default.pa so not use the alsa sink as rtp source, so now 
as expected ALSA fails, but still sends music to remote hosts:

Dec 26 12:56:07 artigo-nic pulseaudio[2834]: alsa-util.c: Error opening PCM device hw:0: No such file or directory

I have powered it off, rebooted etc but no luck. Not sure if it is a 
hardware issue of something on the software side.

Any ideas?
Thanks.
