Headphone volume randomly jumps

I've had the following issue that has happened for the last year or so off and on, but has gotten much worse recently. I'm running Windows 11. I have a set of headphones that has no volume control. These headphones are USB headphones, plugged in to my computer via a USB hub. The only way I have to control the volume is via the master volume, which I usually set to around 5-8 to be reasonable. Randomly the volume level goes way up, although the posted level remains at whatever I set it to previously. If I change the volume, it will change back to a more reasonable level, until something trigger
