Testing all morning, on my particular setup, ROG Ally X running latest Bazzite update (or any of the most recent builds which I tried rebasing to) audio is unusable over HDMI after waking from sleep.
I've tried using the decky plug in 'pause games' which did not help, and I've poked around with a few different pulseaudio / pipewire settings reccomended online for similar issues. No good.
Could it be connected to the dock I'm using? Or the HDMI cable itself? Is that even possible if it works fine from a fresh boot?
wake from sleep problems are usually a matter of platform support, unfortunately these devices are already unstable coming out of sleep so you'll have to use trial and error if you want something to point at specifically
It seems fine if only using the Ally handheld, so it's has to be something to do with a service resuming from sleep that handles hdmi output. Anywhere you can suggest I start poking around?
