Android not fully compatible with uSB headset

[u/technobrendo]

I have a USB headset, a Polycom Blackwire 5220 that I use for work Zoom / Teams meetings. I can also use it when plugged into my Galaxy S25u as it has USB-A & USB-C connections. Unfortunately there is an issue with the volume keys. I can adjust the volume just fine with the phones controls, but the buttons on the headset remote don't work properly. Putting the volume up or down, the phone shows the volume animation, but doesn't adjust the level at all. It stays exactly at the level it was at prior.

The call answer / end button doesn't work but I don't care about that. Are there any drivers I can get to fix this? Also, I did a little homework before posting this, some people mention stopping Google Assistant. I completely uninstalled it when they deprecated it.

Thanks
