When LAV Video enables HDR passthrough, the GPU switches color/bit-depth modes, which temporarily resets the HDMI audio device and causes “no sound” at playback start.

Disabling LAV Video prevents this HDR mode switch, so the audio device never drops.

You can avoid the issue by enabling HDR before playback, disabling auto HDR passthrough, or using tone-mapping instead.

We're going to write a short guide on how to do these steps in the coming days.
