[MPlayer-users] weird behaviour with alsa

[c q]

I've found this funny error. I kept on getting this alsa-init error about
period size undefined. It was defined in my .asoundrc so I just got rid of
it and the same error came up. .asoundrc also has a global equivalent
asound.conf in /etc/. If I set the period_size in asound.conf and exclude
it from my local .asoundrc I get no errors and sound functions fine.
However if it is excluded from either, or add it to .asoundrc, it does not
function. Has anyone else experienced this? 
Cheers 
Chris
