So I'm dealing with an extremely frustrating issue with my Sennheiser GSX 1000.
Up until recently, I've been using my GSX 1000 as a DAC because I like it's virtual 7.1 for gaming, but also because it has a very convenient audio output switch built in to it. Basically, my audio output all fed through the GSX, then one line went out for headphones, and the other fed off to a Fosi Audio amp that I have bookshelf speakers connected to. The whole setup worked incredibly well... until now.
All of a sudden my sound just stopped working altogether. No audio output for both the speakers and the mic. Also, I noticed that the windows volume control was disconnected from the GSX. (They used to work in sync) So I thought at first it was something simple like a Windows source issue, but quickly ruled that out. Then I did all the standard driver updates and checking for any conflicts, but couldn't find any issues. Uninstalled nVidia broadcast and even disabled all other sound sources to no avail.
This is where things get really bizarre... The GSX is driverless, but I figured maybe there's a firmware update that would help. I grabbed the Sennheiser updater tool from EPOS and sure enough, there was an update. Once completed, everything became much worse. Now, somehow, windows displays the GSX as two completely unique audio output options. One is for the headphones, the other for the speakers.

This appears to have completely disabled the ability to switch sources with the GSX. The 'headset' output now works no matter what is plugged in to it, but I can't get audio of any kind out of the 'speaker' output. This holds true if I swap to it with either Windows settings or the button on the GSX itself. No combination of anything I do will get audio working from the speaker output.
Bizarrely though, if the 'headset' option is selected, the Windows volume control syncs with the GSX. (Even though no sound actually comes out) But when I'm on the 'speaker' output, the windows volume control is completely independent of the GSX. This makes using it even as purely a headset DAC a lesson in frustration.
I don't know if the GSX has simply died on me, or if there's something going on I'm missing, or if this firmware update has simply pooched it regardless. But needless to say I'm incredibly frustrated and not sure if I should just be looking for another option.
