it seems that running ctxfihlp.exe as admin might change something, I hope it won't freeze
I was right
when using entertainment it shows a little windows security UAC when I switch to HEADPHONES like it needs permission, I think that's what screw up the system and freeze the driver, it doesn't have permission for such support, HEADPHONES doesn't actually exist in the windows, it's STEREO but it's crashing the driver
So finally running Ctxfihlp.exe as admin actually let it run properly, it does weird switching, but it doesn't sync if I put Headphones, it stays 7.1, the only issue now is ctxfihlp.exe always reset to 2.1 when I log off/on or restart or switch to entertainment
