The configuration seems fine, so I'd guess it's the hardware. When you
originally only had a stereo sink, did this problem not occur? If you
change the Speaker mapping to only have two channels, does the problem
go away?

You can use this to test how direct alsa access works:

    speaker-test --device=hw:X --channels=12

That will open the device with 12 channels and play noise to each
channel separately.
