I see why my audio get screwed so many times.
High Fidelity does not have trhe option to detect the default playback device.
What we need in the audio settings is option to let high fidelity automatic switch to the default playback device. You can run steam, and always run high fidelity from the desktop installer. (avoid steam version, because you cannot run the steam version without starting steam)
Request: Option in audio so high fidelity checks the windows default playback device and set the playback in high fidelity to that. That way it’s following the steamVR change. High fidelity is not doing that now.
