I just bought a Sennheiser GSP 370 upgraded from a Logitech G933 and I've encountered quite an interesting bug.
With the GSP 370, whenever I mute Windows either through my keyboards mute button or when I mute directly through Windows... Nothing happens. Windows correctly detects that it's muted by showing the mute icon on the taskbar and in the volume mixer, but it still plays audio. When I plug in my G933s the issue is gone as Windows correctly doesn't play any audio when muted. If I switch to my monitors onboard speakers, the issue is gone, it's muted when it's suppoised to be muted. Increasing or decreasing the volume works as intended and will mute when I pull the audio to zero through volume mixer.
Maybe this is a known issue with the GSP370s, but I haven't found anything to support this theory through Google or the Sennheiser forums. I've tried updating my mobo's audio drivers, updating the GSP370s firmware and the Sennheiser gaming suite that goes with it.
I'd be very grateful if someone would try helping me with this issue. I really miss being quickly able to mute my sound. Thanks
