[Bug 86351] HDMI audio garbled output on Radeon R9 280X

https://bugzilla.kernel.org/show_bug.cgi?id=86351

--- Comment #32 from lethalwp@gmail.com --- It's still not ok for me with rx550 on a core2duo. The HBR audio now starts playing to the audio receiver thanks to the fix.

But the sound is "flickering", it improves a lot by maximizing the audio buffer, and even more by putting load on the cpu(vm), but it's still not usable.

Couldn't reproduce this issue on a rx550+4770k. So it could be linked to older motherboards/cpus slower scheduling or something?

Iirc, i also tried an rxvega on the core2duo, couldn't reproduce it either.

I still have tests to do: retry it with another linux distro on the old computer. I really don't understand what or why anymore.
