I still have not been able to get spdif working with Myth on my new 
frontend. I can get it to work with mplayer using the alsa1x:spdif 
option. I am using the intel8x0 chip. What device do I use to get oss 
emulation access? I have tried /dev/adsp0 but it says No Such Device. 
Why won't myth work with spdif if mplayer will? I tried the ALSA:spdif 
option as the device but get a floating point exception.
