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:

    Chaintech AV-710, ICE1724
    4.0 Surround output to Front and Rear speakers
    Chaintech AV-710, ICE1724
    4.1 Surround output to Front, Rear and Subwoofer speakers
    Chaintech AV-710, ICE1724
    5.0 Surround output to Front, Center and Rear speakers
    Chaintech AV-710, ICE1724
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers
    Chaintech AV-710, ICE1724
    7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
    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.
