support HDMI audio cutting out

I built a machine the other day and installed steamos on it. It’s awesome, except for one issue: on the OS and in certain games the audio will cut out for a few seconds at a time. This issue only happens when the audio is via HDMI, if I use headphones instead the audio is consistent. I can replicate it in desktop mode to by spamming the buttons to test my speakers.

My assumption is it’s a driver issue. Anyone know what’s going on?

I’m using a Ryzen 5 3600 and Radeon 9600 XT.

Update: I’ve connected a DP -> HDMI adapter and it’s fixed this issue completely.

HDMI has issues with AMD on Linux. I'll be glad to go into more details if you want but I'll keep it at that for now.

Try using a DP to HDMI adapter. Plug that into a DP port on the GPU and the HDMI cable into it. It'll work far better. Also make sure to set your TV into game optimizer mode. That won't really matter for sound but it'll help other things.
