Hi,
I'm trying to find a straight answer to this question in the forums. Is anyone using pd on Rpi with more than two channels of audio output? and is it sounding ok?
I did (aureon usb 7.1), and it sound bad as soon as more than 2 channels are involved. Even with huge latency and buffers. Lowering the samplerate helps, but does not fix.
I also tried outputting with more than 2 channels via HDMI, it exhibits the same problem. So a hdmi to analog audio won't help.
It's not pd that's in cause, it fails too with omxplayer.
I believe there MIGHT be a way : output DTS or AC3 straight to hardware, maybe embedded in a blank video sequence. But then your options are rather limited for what you can do with pd.
