[mythtv-users] Audigy AC3/SPDIF out?

[Chris Germano]

How would I go about setting up AC3/SPDIF out on an Audigy?

I'm currently running Alsa with an Audigy (EMU10K2 chipset, ya i know it's
the Audigy 2 chipset). I'm using it normaly right now and it works. However
I want to use the SPDIF out on the back of the card for the various Myth
Plugins, and of course TV. I'm recording TV with btaudio at 32khz right now
(it's hardware locked) so will that be a problem or does it automaticaly
support or upsample it? Once it is setup do I have to force i to use it or
point it to the proper /dev? ie MythVideo calls to mplayer for AC3?
