I have my Xbox connected to my Anthem D2 via HDMI. Everything is working fine.
However, whenever I try to play audio files, sent via WMP 11 Connect, the Xbox is not sending them in PCM 2.0 format, but rather 5.1 format. The next effect is that I'm only getting stereo sound from my mains and nothing from the rest of my speakers, since the D2 thinks it's getting a multichannel signal.
If it were to receive a 2.0 signal, then it would be able to apply its processing to send the signal through all of my speakers.
Anyone find a way to work around this?
