Hello.
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 have tried with a cmedia cm6202 6 channel (5.1) but can only get it to work adequately if I deactivate output multiple audio channels (more than 2). I need at least 6 channels and preferably 8.
Has anyone tried to plug in several cheap stereo usb interfaces onto the Rpi through a hub, and setting the different interfaces as multi outs in audio settings, in order to multiply the outputs? Does this work?
I would also like to know if anyone has tried an hdmi decoder with more than 2 channels from pd, and whether this actually works. I'm confused about how multichannel sound is handled in hdmi, but would live to know if there is a possibility of outputing 8 channels of analog audio if, say, one of these hdmi decoders were plugged onto the rpi: http://www.allaboutadapters.com/hddodtsdihdo.html
If nothing else works, I'm considering just buying 3 more raspberry pis, and linking them somehow... I just want to make sure I'm not missing something, before I spend money on these.
Many thanks....
Hi,

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.
