Comment 31 for bug 1834771

Absolutely the same behavior here. Last working kernel is 5.0.0-15.
(5.3 is not working here as well)

I've been messing around with this annoying bug for months (using headphones because my display sound is gone) until someone pointed me to this bug report today. It is ridiculous to completely take the hdmi sound from all AMD users just because too much choice could confuse some people. For now I'll stay with 5.0.0-15 but please fix this issue soon!

By the way, I agree with my predecessor. I also don't want to use the proprietary driver. The free driver (with at that time flawlessly working hdmi sound) was the reason for buying AMD graphics.
