Title: Can't get multi-channel. Stereo only
Post by: Snookboy on December 01, 2011, 10:08:14 am

Pretty new to JRiver so I'm sure I'm missing something obvious here but I've moved to a new machine and cannot get 5.1 no matter what I do.  It was working fine on previous machine.  Same sound card.  Main difference is going from a P68 to Z68 chipset on the motherboard.  I can get 5.1 in other programs such as VLC.

I am going out an Asus Xonar D2X sound card from SPDIF to an external reciever. This is the same set up on the old machine. 

I have used ASIO, WASAPI Event with same results.  I have configured Output in DSP to use source.  I have tried selecting to fource 5.1 channels.  I've tried not checking DSP Output.  I've tried everything.  All I get is 2.0 Stereo. 

Any idea what I am missing here?  As I mentioned, I had it working fine before with very similar setup; really only thing changed is the motherboard to a Z68 chipset and I can get 5.1 on this setup in other programs.  TIA!

SPDIF only supports surround sound if you encode as Dolby Digital.

You can tell Media Center to do this in DSP Studio > Output Format.

You can also bitstream Dolby Digital inside a movie, but this circumvents any audio features in the program.

Matt, thanks for the quick reply. 

I see now what you mean on the output.  If I select under "Channels" to 5.1 I then have the option to output as DD.  This does work when selecting WASAPI Event, but is still 2.0 under ASIO.  I'm pretty darn sure I used ASIO and selected source channels before and was able to output 5.1 DD. 

With bitstreaming I can leave it as "source channels" and it works fine with WASAPI Event Style, but is problematic with ASIO.  It worked, and then it didn't; no sound.  So maybe I have ASIO driver issues, but it's the same driver.  (I did increase the buffer).

I'm fine with bitstreaming as the only thing I am losing is VideoClock; as all other options lost are being handled by my receiver. 

I know I was running under ASIO drivers on old machine.  What do I lose by using WASAPI Event instead?  I bit more delay/jitter?
