Steps to reproduce:
I have tried to play back a multichannel wav file with the Web Audio Api on MacOS Big Sur (more than 8 channels, i.e. 12 channels)
Actual results:
There was distorted sound. If i change the number of the channels of the wav file less or eqal to 8 channels, there is no unwanted distortion. If i use an multichannel opus files (for example 12 channels) all works nice, there is no distortion. At Google Chrome or Opera also the 12 channel wav files work!
Expected results:
Distortion-free playback for multichannel wav input files with more than 8 channels.

I can reproduce with this file, thanks. Sounds like a decoder or demuxer bug, we can't even play it back using a regular HTMLMediaElement
.
Triaging, please adjust if needed.
