Those pesky audio issues seems to have come back in the last update, so we've uploaded another fix. For a bit more detail, we believe this is caused on some audio drivers when the Windows audio device sample rate is set to 44.1kHz, but not at 48kHz. Now it should work properly at either rate.
Update 1.04
Thank you all for the support and feedback you've given, we're so glad that you've been enjoying the experience! We've made an update to address some of the most requested controller-related features:
Valve Index controller support
Windows Mixed Reality controller support
New option: disable snap rotation, turning it to smooth rotate (only available on controllers with joysticks)
New option: designate rotation to a single controller (i.e. forward movement only on left controller, rotation only on right)
Update 1.03
Fixed fatal error caused by certain audio device configurations
