I have a 5.1 sound speaker setup and sound is good when I play on monitors, but when I play in VR the sound is bad. The rear speakers produce no sound but the front 3 do, so a rear engined car has almost no engine noise at all, but if i hit the "look behind" button I get the full engine noise through the front centre speaker, which makes sense, but then back to forward view and I get nothing from the rear speakers. Its possible that this is somehow related to openvr_api.dll though I'm not sure how, because I've also noted that if I use a different openvr_api.dll (open composite, in order to use pimax XR) I get the same sound issues even whilst playing on monitors. It seems strange that openvr_api.dll would have any effect on sound when not playing in VR but it does. as an aside, using a different openvr dll disables the ability to choose hrtf profiles when using headphones Thanks for any help
