I have powered speakers connected by USB to Fedora KDE 32 machine.

Until recently everything was fine, until I noticed that say at 50%
volume it plays quieter than before. It actually plays quieter at every
volume level, but at 18% it goes mute completely even though at 19% it’s
nowhere near the minimum.
Also if I use volume control on speakers or using the remote control,
I can’t go lower than 15% - it seems that speakers think that 15% is
Another thing - when I power off/power up speakers they start playing
significantly louder, and after couple seconds they lose decibels. I
would guess that when powered up they start playing at the level I’ve
used to them playing, but something kicks in and they go quieter.
