><br>> The first is a 5.1 with optical that *just works* out of the box with ALSA<br>> and passthrough (no crazy asoundrc files) and the second is a low profile<br>> card that works just as well in case you have a smaller case and are looking<br>

I had this card working fine for AC3 and DTS files in a previous box.<br>I updated a frontend the other day to digital output (and 0.21) , and<br>put in this card. I have digital audio working, but it's in stereo.<br>
I have tried speaker-test, but I only get audio from the front left<br>and front right channels. Is there any direction you can point me in<br>to get multi-channel working over the SPDIF?<br>

<div> </div>I never had to do much more than put in the card, set ALSA:default in the Myth config, make sure the IEC958 or whatever is unmuted in alsa-mixer and set Myth to AC3 passthrough.</div>
