Using LAVFilters-0.70.0-10, MPC-BE.1.5.1.2641.x64, and madVR v0.91.10 playing various files that I get audio out of sync issues. I have to skip back and forth for the audio to get back in sync. Which program in the chain controls the audio sync so I can troubleshoot? Thanks.

Potentially it could be anything I guess, it could even depend on the video format.

Can i highjack this thread? So i noticed than using MPC-HC with LAV-Quicksync decoder for H264 VFR video files cause audio out of sync issue. I searched and this issue was already noticed in past and reported but looks like not fixed to this date. Is this Intel related issue?

Changing LAV decoder to CUVID(NVIDIA-DXVA2) or software fix the issue.

Then do that?
QuickSync is generally not recommended.

My NVIDIA Kepler decoder is slower than QuickSync Haswell. QS can decode 4k60 while NVIDIA dont.

BE never keeps sync for me. HC is fine.

I use DXVA CB for both
