I have some problems with this too.
I joined Game Pass for PC and was informed by windows that I needed to update to the newest version for the Game Pass app to work- turned out to be 1903. 😫 I actually hesitated suspecting 1903 as the intended release and having heard of problems with it,
but I figured if there were still issues it would stop short of 1903. My mistake.
Ever since then, my quadrophonic speaker setup doesn't work. I have a soundbar one one output and a set of Soundblaster speakers with a sub for rears on another. However, ever since the update the rears/sub only work when playing the "test" button sound.
Otherwise, it won't play anything from that port. I tried swapping the cables and sure enough, now the rears work and the fronts don't but this makes the system think the rears are fronts and vice versa.
I'm at a loss as to why the speakers would work when playing test sounds but don't with any other type of sound output.
Other things I've tried:
Driver rollback
Drive update
Manual installation of drivers
Generic drivers
Disabling and re-enabling the sound card
Disabling and reenabling the specific output
Disabling all sound effects and advanced sound settings
I could split the one working output but this would only give me stereo, not quad surround 😕
I also looked at the event log for the sound car drivers and found that windows update indeed made changes to my sound car drivers during the update to 1903 last night. I saved the log of these changes before doing anything manually. These changes had to
be Windows Update changes because I happened to be asleep in my chair at the time this happened.
Most frustrating part about this is that I literally paid money to Microsoft to end up with this problem by signing up for Game Pass for PC! And what's worse: there's no going back!
If I had any other choices for gaming and my Rift S I wouldn't be using a Windows system at all. Its a total joke of an OS and has been for quite a while.
As a PC gamer I feel like ive been totally crapped on by Microsoft while they played Console wars with Sony and Nintendo. I was gaming on PC before PlayStation and Xbox existed! Game Pass for PC was my hope that would change- but it's more of the same.
