Volume on DAC starts out amplified since KDE 6

This is sort of a weird one. I use a Dragonfly DAC plugged into the USB of my Linux machine, using KDE 6. Since the upgrade, whenever I first start playing music through it, the volume is super loud, even though it’s set to a low level. If I toggle the level at all, it goes back down to normal.

If unadjusted it’s so loud I’m worried I’ll hurt my ears/the headphones; anyone know what’s up with this/how to fix? It worked fine on KDE 5. (I’m running KDE Neon.)
