Hmm, Alexander is probably correct. Then maybe it would be better to fill with aux channels instead, e g, for 10 channels, change: channel-map = front-left,front-right,rear-left,rear-right,front-center,lfe,side-left,side-right,aux0,aux1 to: channel-map = front-left,front-right,aux0,aux1,aux2,aux3,aux4,aux5,aux6,aux7 ...that should stop output to those channels by default, I believe. -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic
