Unfortunately, this is a problem on all HDMI boards of
which I know. That is, Intel and Nvidia boards supporting
multichannel over HDMI have this issue. The only solution
which I've found here is to remap the surround51 playback
device via /etc/asound.conf.
pcm.!surround50 {
type route
slave.pcm hdmi
slave.channels 6
ttable {
0.0= 1
1.1= 1
2.4= 1
3.5= 1
4.3= 1
}
}
pcm.!surround51 {
type route
slave.pcm hdmi
slave.channels 6
ttable {
0.0= 1
1.1= 1
2.4= 1
3.5= 1
4.3= 1
5.2= 1
}
}
When mplayer encounters a 6 channel stream, it'll use the
surround51 device by default. You will want to check any
other players used.

This is odd I've never had this happen. I do get a half
second of track skip between tracks so track transitions
sound pretty terrible but complete silence, perhaps a
developer will know what this is about. I wonder if the
skip between tracks and the silence problems are related.
IE, is the hardware reset on device open doing more harm
than good?
