I hope I'm just being stupid and someone can point out an obvious solution. I am trying to run stereo source files through MC>Onkyo AV receiver to 7.1 channels. I have been trying to use the DSP Studio and setting Channels to 7.1 (then > Done), but nothing changes. If I set Output Encoding to Dolby Digital, the sound plays through 5.1 speakers, although the DSP panel shows it as playing 3.1; nevertheless, I'm hoping to use all 7.1 channels.
Here are the specs:
MC 34 on Windows 11
HDMI to Onkyo TX-NR676 with 7.1 speakers, set to Direct Output
