Hi Bill,

As Xine (or Mplayer in some special cases) is used for playing DVDs, videos and recorded TV shows, I think you need to set Xine to use the correct output. There are some information on the alsa website http://alsa.opensrc.org/DigitalOut, but I don't know if it will work in LinuxMCE.

You may also try the information here in our wiki http://wiki.linuxmce.org/index.php/Nvidia_CK804 . This worked in my case, although my chipset was slightly different and I had stereo prologic sound but no DTS or AC3 stuff.

I eventually resolved the issue by putting in a turtle beach card with optical spidf built in. This worked immediately and I could use AC3, and DTS.

Seth

I have the M2N SLI-Deluxe mobo and also had sound probs like this using coaxial out. I fixed it by selecting "manual configuration" (instead of "SPDIF Optical" in your case) in the LMCE audio settings (either on the LMCE Launch manager "audio" tab or in LMCE admin -> media directors)

So after you did this, were you able to get AC3 and DTS sound? I am curious because I have another use for the sound card I installed on another system, and would like to get back to using the onboard connector?

Hey Guys,

 It seems You have to do this on 90% of the new boards after of course you turn up the IEC volume in the KDE desktop mixer settings. I am not sure why the iec defaults to pcm output defacto and not bitstream but that just seems the way it is. I have had to set manual settings for a ADI codecs be it Intel based or Nvidia based mainboards. you get full bitstream passthrough after this change with DD (ex) and DTS (es) I have not tried an AAC encoded file. it also works fine with FLAC as all my audio files are.

 rgds,
