Wireless USB Audio earbuds not working SW4 Wireless

Hey guys I recently bought the following earbuds for my PC.

I’m running the latest update of EndeavourOS and I"m able to use my line-out speakers just fine but I cant get the earbuds to work, the receiver is plugged into the USB -c port and I do see the earbuds show up in the sound settings as Digital SW4 Wireless but when I select it I don’t hear any sound.

I can see the volume level move but no sound. They work fine when I boot into Windows.

Any idea what the issue could be?
