I have a Sinovoice UAC-05 which identifies like this uaudio0 at uhub0 port 2 configuration 1 interface 0: ABC C-Media USB Headphone Set, rev 1.10/1.00, addr 2 uaudio0: audio rev 1.00, 8 mixer controls audio0 at uaudio0 it is connected to my NAD T-760 receiver using a toslink (optical) cable. In the following examples I use "Gladiator" (region 2). To get DTS on the receiver: mplayer dvd:// To get Dolby Digital on the receiver: mplayer -ac hwac3 -aid 128 dvd:// (On "Shrek" (region 1) I had to use -aid to get DTS.) -ac hwac3 tells mplayer to let the soundcard do the work and not do it in software. To find the "aid" (audio id) I run mplayer with -v and look for something like this. DVD successfully opened. [open] audio stream: 0 audio format: ac3 (5.1) language: en aid: 128 [open] audio stream: 1 audio format: dts (5.1) language: en aid: 137 [open] audio stream: 2 audio format: ac3 (stereo) language: en aid: 130 Hope this helps.
