[MPlayer-users] Subject: rc5 audio tests w/ surround 5.1 + 6 channels + alsa 0.9.2

Hi,

Just a quick update. I have noticed that if I play a DVD with the 5.1 options 
and the center output is not in the center speaker, I can repeatedly step 
backwards and forward with the arrow keys and finally get audio output in the 
center.

Seems like a bug. How may I diagnose this problem further?

TIA.
Hugo.
