OSS4 Ubuntu - Channels problems

Postby rokyronnie » Sun Feb 13, 2011 9:11 pm

Hi everyone, this is my first post here, so excuse me if it's not the right place.
I've OSS4 on Ubuntu 10.10, my sound card is Creative Sound Blaster Audigy 2 SE, and I discovered that the volume level for the Central and Subwoofer it's every time the same, even if I mute my channels.Is that right?

Tell me what I can do....

Thanks.

"Is that right?"

I don't know. Can you post output of 'ossmix -a' and of 'ossinfo -v3'? It might help a bit. Also, if your audigy is using the analog output, adding "audigy_digital_din=1" line to /usr/lib/oss/conf/oss_sblive.conf might help (requiring OSS restart: "sudo soundoff" and "sudo soundon").
