My Evga Z15 I recently got has an issue, where you have to turn the volume wheel a few rotations (sometimes more, sometimes less) to change the volume one step. So it is pretty much impossible, to quickly change the volume. When I first got it the volume worked as expected, but I installed the EVGA Unleash software, which installed a firmware update and I think the issue might have appeared after that.
The only similar issue I found is this reddit post: with a video which looks exactly like it is for me.
Is this a hardware issue or a firmware issue?
I also tried plugging it into my android phone, to exclude the possibility of a windows issue and it had the same behaviour there.
