Hi, I'm writing a profile for a multi-channel USB-Audio interface. It has different input/output channel types (mic, line, S/PDIF) but they are all exposed as one multi-channel device by ALSA. The current workaround is to use e.g. channel-map = front-left,front-right,rear-left,rear-right,front-center,aux6,aux7,aux8,aux9,aux10 to disable channels 6-10 (aux6-aux10). The channels are not used, but shown e.g. in pavucontrol. Is there any other way to disable channels completely in a profile mapping? Thanx for any help, Renne
