Audio lags during playback on Quest

[Alnpfi]

I'm playing mkv files off of a USB drive plugged into my Quest with 4xvr. The only issue I'm having is the audio starts to go out of synch after 45min- 1 hour. I pause then play and it's fine again. Any ideas? Not a huge problem but a little annoying. Thanks!

It sounds like a problem with 4XVR or the Quest itself.
