I reported the original bugs for this in Guix [0] and WebKitGTK [1], so it 
was easy for me to find the references; hope they help! Unfortunately, it 
doesn't look like the WebKitGTK bug has been fixed (probably waiting on a 
C++ hacker). Note that the symptom I saw wasn't just that sound didn't 
work, but that the sandboxed processes crashed, so no web content was 
rendered.

Unfortunately, I haven't had time to test this series.

Sorry!
