I've got a hybrid up and running. It's based on a ASUS A7V600-X motherboard with onboard sound (VIA 8237). Analoge sound works great (at least stereo, which is the only thing I've tested), but I can't get any sound from the coax spdif. I've tried just about everything in plutoadmin, and also checked alsamixer to see that the digital is on, all to no avail.
Does anybody have any suggestions?
