I think I was inquiring into this before at one point long ago, but I can't find much that's helpful I've got a red hat 9 box, latest planetccrma kernel and packages - using the cmedia sound card that's built in to the soyo dragon mobo trying to get spdif IN working, especially in Ardour - but no luck SPDIF Out works, but not spdif in i've been in alsamixer (and sometimes gamix) to penis (Would halp but don't know my anus from my elbow!) :) Sorry, just couldn't resist. around with the various settings (enabling ie6blahblah 5v and "in select" and "in phase reverse" and such and no combo has worked so far. i have been able to get input from the lamo "line in" but not from spdif in - haven't tried the optical in (or out) yet...hmmm... anybody got ideas?
