NDI video and USB audio out of sync

Hi every one.

I have a small setup for a church. We have no internet connection on the temple. We record the service and when we get home, the service is uploaded to YouTube.

1. We have a PTZ NDI camera connected directly to the Laptop. Works fine on OBS. The video feed from the IP web-page from the PTZ camera runs with no latency. The video signal is the same on NDI Video Monitor.
2. Also a XAir18 from Behringer and the audio we get goes to the computer through USB.

That is all we need.

The OBS setup in NDI video source is:
Bandwidth: Highest​
Request hard. acc.: ON​
Latency mode: Low​

When the recording starts the audio is synchronized. But after a few minutes, the video gets out of synch and much after from the audio.

What can I do to get a synched audio and video all through the recording?
I have tried to capture the window from NDI Video Monitor, but is the quality the same?
