The usb headphones stop working when I turn up or down the volume

HI my sennheiser usb headphones works nice, but when I change volume level.
Mic continue to work but there is not sound.

I can’t get it back in settings, or with reconnect and connect.

Are you on Fedora 33 or 34? I have you tested them on any other Linux systems? Non-Linux systems?

Fedora 34. Headphones works fine, I use it one year on Fedora 33 without any problems. It works on my mac too. Even in fedora 34, it works fine, but after volume up/down (using keyboard shortcut), it stop, and I need to disconnect/connect it multiple times to get it work again.
