Thank you for your responses, everyone.
Hopefully, Framework can do some testing and find a solution to this. Or at the very least tell us what the cause is.
It may be the case that this has only happened to me when I have been using my headphones, but I often use my headphones, so I don’t know if it is the cause. However, with @pkunk and @Michael_Perrotta saying they also use Bluetooth audio devices, I wonder if it is specific to that?
Has it ever happened to anyone whilst they didn’t have a Bluetooth audio device connected?
