Was having a few issues with multichannel last night. Can't seem to replicate the issue but basically I was only get output from my L&R channels while watching movies with a Dolby soundtrack. Ended up having to select "Dolby" under DSP_Output Encoding to get sound out of all 6 channels.
Anyway - all seems better today, but I just wanted to verify the proper setup for JRiver
DSP>Output Encoding: Set this to "None" which will allow JRiver to use audio processing offered by Media Center. This includes VideoClock, Room Correction,parametric equalization, normalization, etc
DSP>Channels: Set this to the number of channels in your system (5.1 in my case). OR should this be set to "source number of channels"
Any other sound setup that I should consider? (Eventually I will get to the "Room Correction" and "Parametric Equalization" and will turn off any Audyssey processing in the AVR)
