my AV receiver is quite old, do not have HDMI.
I have hook the media player using the SPDIF outpu. Since i have used it for movies with true 5 chaneles audio, i do not change settings, but i will look it up !!
I am on the virgo to acquire an used sound card so i can feed with signal to the receiver. Im not sure how the 2 digital sound processing ( first made by sound card chipset, second made by receiver chipset ) will behave !
