Public bug reported:
I've been having ongoing issues with pulse and my nvidia video card
doing hdmi audio, so I thought I'd try using my builtin intel HDMI port
for audio instead. However, when I switch the HDMI cable to that port,
and select it in pulse, all the audio sounds crackly and garbled, like
it's trying to play twice as many samples per second as it should. given
this is with open source drivers, this may be a kernel issue and not a
pulse issue, but I'm not sure how to fully determine that.
