[alsa-devel] Noise on rear speaker when switching from 2.0 to 5.1 sound

[Felix Rauscher]

Hello,

I have a Hercules Muse 5.1 DVD (C-Media PCI CMI8738-MC6). I have a problem 
when a running xine (e.g xineliboutput from vdr) switches from 2.0 to 5.1 
output. Then the sound quality of the rear speakers is terrible. There is a 
noise on the rear speakers.

If I start the xineliboutput-client when vdr already plays a programme with a 
5.1 sound track, the quality is ok. It looks like the switching between 2.0 
to 5.1 is a problem. 

Thank you for your help!

Felix
