This signature has been around for awhile, but seems to be spiking in 115. Possible regression from bug 1833633?

[Ryan VanderMeulen [:RyanVM]]

Bug 1838241 spiked around the same time - maybe this is another signature falling under that?

I haven't had a chance to dig into this in detail yet, but it appears to be a slightly different issue to bug 1838241 although it does seem related to the render thread lifetime changes that landed in bug 1833633. In this case, it looks like the render thread is still actively processing audio buffers (on a stopped stream?) while another thread is in the middle of a stream start/reconfigure device sequence. ni? myself to investigate further when I have time.

I hit this crash immediately after turning off my Bluetooth headphones while listening to Spotify. Unfortunately, I wasn't able to reproduce the crash.
