Panic while playing video at half of the volume level range

I am running Fedora Asahi Remix 39 on my m1 MBP 14" and really enjoying the recently released speaker support (Awesome work, btw!). Today I noticed that, while I was listening to a video at slightly above half of the volume level range, the sound cut off for a bit (it didn't feel too loud either) and then restarted playing at a lower volume level.

Looking at it it seems that speakersafetyd hit an error in an unwrap() call.

I hope this is helpful. Other than this minor crash I have to say that the speakers have been working flawlessly and the computer sounds even better than on macOS! Thank you for making it possible to use Linux on these machines!
