I recently decided to make the move from gaming headset to headphones. I purchased the Sound Blaster ZXR sound card intending to use the Optical In/Out pass through. This is my problem:
In my XB1's sound settings, I select Bitstream out (Either DTS or Dolby, doesn't matter, results are the same), the optical cable is plugged into an optical switch, which is plugged into the Optical-In on my sound card. When I check the box for "Listen to this device", all I hear is horrible electronic buzzing. If I connect the Xbox directly to the sound card (bypassing the switch, same results, so it's not the switch). I even tried my other XB1. Same deal.
The first few times I tried stereo uncompressed, I couldn't hear anything, but it's working now. I may not have had my volume high enough initially because I do have to turn it up pretty high to hear sound. But I DO get sound.
I know, I know, just be happy that you have sound, right? After the hours that I spent obsessing over all of this before I got sound through stereo uncompressed, I'm elated to hear anything at all. The real b!tch of it is that when I switch to my PS4 (running off the exact same optical switch) I can use bitstream DTS and Dolby, NO problem. What??? My PS4 pretty much serves as a DVD player that I occasionally play Destiny on with my ONE friend who doesn't own an XB.
If I plug my XB1 directly into my Z906 speakers, I can use any format. That's great, except the whole point of this is to be able to use my headphones while playing FPS games, so... meh.
The sound card has all the latest drivers, and my XB1 is up to date. I'm just throwing this out there because I know the Sound Blaster Z series is REALLY popular, and a lot of folks are streaming and have both consoles and a PC. I can't be the only person who's run into this, and somebody out there in Internet land may have already conquered this final boss, or can maybe explain what the problem is and/or why my PS4 works. Share your knowledge with me, senpai(s)!
I've asked this question everywhere I can think of, including the Xbox forums and Xbox reddit. I'm asking here because I'm trying to come at it from all sides! And this is the console gaming headphone thread...
