I am getting frustrated now. I have a big noisy backend in my living 
room because it is the only thing I can watch recorded shows on. I built 
a frontend using the MSI 865. I just got one of two things working 
tonight that I needed before I can move the backend and start using the 
frontend. I was tired of waiting for interlace with NVidia so I bought a 
cheap SIS 315 card and had 1920x1080i working in about 10 minutes. Now 
all I need is SPDIF to work. I can use mplayer and -ao alsa1x:spdif and 
it works great. Myth still does not work with SPDIF. I just get audio 
out the headset. My question is, is anyone really looking into this or 
should I get another Audigy card that I know works with SPDIF. The 
frontend is running the latest CVS and uses an Intel 8x0 chipset for 
audio. The ALSA:spdif is no longer giving me floating point errors, it 
just says, Unable to playback audio, Continue anyway?
