Thanks I think I understand it a bit more, at least I hope I do. I
think my problem comes when I try and find the name of my device via
the aplay -L it looks completely different then everyone elses:
surround40:CARD=AV710,DEV=0
Chaintech AV-710, ICE1724
4.0 Surround output to Front and Rear speakers
surround41:CARD=AV710,DEV=0
Chaintech AV-710, ICE1724
4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=AV710,DEV=0
Chaintech AV-710, ICE1724
5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=AV710,DEV=0
Chaintech AV-710, ICE1724
5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=AV710,DEV=0
Chaintech AV-710, ICE1724
7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
iec958:CARD=AV710,DEV=0
Chaintech AV-710, ICE1724
IEC958 (S/PDIF) Digital Audio Output
Which I guess is ok, because I should be able to specific the name
when I try and play something. however when I do that using aplay (or
mplayer), I get an error, which sort of stops me dead in my tracks.
aplay -D iec958 english.au
Playing Sparc Audio 'english.au' : Mu-Law, Rate 8000 Hz, Mono
aplay: set_params:900: Sample format non available
I get that error no matter what I pass in for D. So now I'm back where
I started.
