After automatically updating to the new Playerfab Version 7.0.5.6 today, I cannot select any Windows Audio Devices in Audio Settings anymore - all three dropdown menus do not show any devices:

I was using “Output Mode = Analog” and “Output Device = DIRECTSOUND” before and so there is of course no audio playback anymore.
Also my HDR Display does not activate HDR Mode anymore when playing a HDR Video Source.
After downgrading back to Playerfab Version 7.0.5.5, both issues are gone…
