Indeed.
But it's more than that. Even if I generate output on the other
channels (i.e. with mplayer's channel mapping), the amp still only
sees 2.0 channels.
To my knowledge that is because sp/dif bandwidth is too low for more
that 2 channels unless they are compressed into an AC3 stream first.
So the only way to actually _get_ all the channels my hardware can
generate to my amp seems to be encoding the whole bunch into an AC3
stream in real time.
Regards,
Phil
