Look around for PCM, Stereo, 5.1 and others in the PS4. If all fail then it's a bum not so good adapter.
I just bought a sound extractor from Amazon so I can use the Optical cord to connect to the Sound bar coming from my PS4. I have the PS4 slim with no optical cord outlet so the extractor was necessary.
The audio extractor works but the sounds fades in and out every other second. Gives you a quick headache if you listen to it for 30 secs. Curious if it's a signal issue or if Bose has some sort of compatibility issue. Any help would be greatly appreciated!!
