I have the Sennheiser 363d headphones and have only had them for a few months when the audio started to randomly cut out, but then it would come back in immediately. If you own this pair of headphones you know it runs into a Dolby digital virtual surround sound card and then it connects via usb(also comes with a usb extender in the package). Later on the cutting out would get worse, not by its frequency to occur, but its duration. Eventually it got so bad, the only way to fix it was to unplug the usb extender, essentially unplugging the device from the computer and plugging it back in. I tried using different usb ports, but the problem still kept occurring. After this became a annoying enough, i unplugged it from the usb extender all together and just ran it to a usb port directly. This solved an issue where it would cut out for long periods of time, but then the cutting out began again and i would just have to wait about 2-3 minutes for the sound to return, because unplugging it no longer helped. I thought that maybe I just got a bad product, so I ordered another pair and the first day that I tried to use them(I am using the usb extender at this point again, if that matters(a brand new one though)) and the sound issue started all over again, where the only way for me to get sound back is to unplug and replug the heapones. I have also tried uninstalling and reinstalling the 3D G4ME1 drivers. Thank you for responses.(I do not use a dedicated soundcard)
I would disconnect the 3D Game 1 and plug the headset directly into the onboard sound and mic and see what difference that makes. If the cutting out goes away then you know it's the 3D Game 1 module.
When I purchased the new pair, it came with another virtual surround sound card and that was the one I was using when it began cutting out again, which leads me to believe it isn't a problem with the headphones, but i am not certain.
It sounds like a loose connection or something isn't fitting just right so that's why I suggested bypassing the module to see if the headphones work ok without it cutting out. If you can get the same performance with bypassing the module then I would go with that.
