Speakers volume lower than it should be

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

Bus 003 Device 002: ID 0d8c:0043 C-Media Electronics, Inc. TUK by Kanto

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
the 0%.
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.

Not sure what I could do there. For example at 5, 10 or 15% master volume I do see blue line jumping, but no sound is coming out from the speakers.

It gave me an idea to plug in headphones to the speakers (there’s 3.5mm out), and I do hear sound playing even at 5%.

If I do the same experiment and turn off/turn on speakers headphones do start playing louder and after a second go quieter as well.
