Hi all, I recently switched from an AMD Radeon RX 480 to an AMD Radeon RX 6700XT and ever since then my audio over HDMI intermittently drops out when playing videos in Firefox.
Funnily enough, I noticed that if I open PulseAudio Volume Control and the window is ever so slightly visible, the audio works flawlessly.
Here's a video clip, notice how the window isn't in the foreground, and as soon as the window is fully covered by Firefox, my audio starts cutting out.
A few other observations:
- I get similar issues playing videos in MPV
- Audio from games doesn't seem to drop
I'm honestly not sure how to figure out where exactly the audio gets dropped. I'm using Pipewire + Wireplumber and all the relevant packages, everything at default configuration (to my knowledge).
Anyone got an idea on how to track it down?
