trying to get passthrough to work... i've a USB soundcard with an optical out (HP Microserver/nVidia card as HTPC).
this is cause i've an old receiver which hasn't HDMI.
anyhat this used to work on eden "custom audio device". i've since upgraded - but now passthrough doesn't seem to work - only 2 channel/prologic sound :-(
if i play a DTS wav sample like so, receiver lights up "DTS" and plays flawlessly:
aplay -l yields:
aplay-L
if i set my xbmc audio settings as described on the wiki i get double/halfspeed video with no sound
..and i've searched the forums and there is prolly some .asoundrc or /etc/asound.conf trickery involved
i just have no idea what i'm supposed to do - am no linux guru so any help/input would be greatly appreciated
