since i'm using alsa CVS for driver, kernel and lib; i'll use utils from CVS 
as well...

didn't know that, in the previous versions, i know that all these peaks were 
listed as mono sliders, not partly mono and stereo...

vortexcontrol looks nice, from what alsa CVS package is that?

thanks for the info, but since i'm not using SPDIF, this was never any 
relevance for me

actually, this one warning has been there for quite some time, i donno if it's 
emu10k1 or au8810... (i think even in 32bit, not sure about that), when 
storing it, modprobe -r and modprobe again, and restoring, the warning 
stays...

> Your /etc/asound.state seem OK and the equalizer is OFF.

never used the equalizer, i wasn't able to put the whole asound.state file, (i 
removed the emu10k1 stuff), cause the size of the mail was too large...

I'm going to try to do the same thing with xine and CVS aplay, see what 
happens...
