Subject: Re: Q: Why I do have to restart alsa everytime after a resume from
disk/ram ? Is this alsa- or kernel or config related??
Hy,
I mean I have to
%/etc/init.d/alsa-utils restart
so that I could hear music again. The music is still played after
resume (ogg123, mpg321, xmms etc), but without any sound.
The libpulse0 is the latest unstable package I found, other
pulse-packages are not installed. And pulseaudio is only be used, when
I use skype, but this is rarely used by me.
here are some hardware infos now at first:

I have logged lspic -vvvxxx before and after a s2ram, before
/etc/init.d/alsa-utils restart and after that command.
Attaching the lspci after a resume from ram and the diff after restart
alsa-utils. Also attaching the
/proc/asound/card0/codec97#0/ac97#0-0+regs after resume and after the
restart alsa-utils.
cheers

I searched for an update for pulseaudio, but I have the latest version
ii libpulse0 0.9.21-1
But as I mentioned above, I am not using pulseaudio plugins (only when
using skype). I used the mpg321 or ogg123 commandlinetools for hearing
some music
