Audio is unrelated to this bug. In my reproduction scripts, I do not output any audio at all. The video-at-3-fps replay that I use for reproduction seems to just trigger a certain pattern of the memory- and shader-clocks getting increased/decreased (with dynamic power management being enabled) that makes the occurrence of this bug likely. Any other GPU-usage pattern that triggers a lot of memory/shader clock changes seems to also increase the crash likelihood - manual use of some web-browser where GPU load spikes are caused a few times per second seems to be also a scenario where this bug is triggered now and then.
