Audio out of sync after encode vfr

[Persian]

I have some movies in variable frame rate mode.
When I encode it, the audio and the video are out of sync.
I tried the following methods but they did not work.
1. Enabling: "Config->Automation->On Load->Always extract time codes from input"
2. Enabling: "Config->Internals->Prefer Original->Frame rate"
How can I fix this problem?
