How to start video synchron to audio?

Hello,

i have 4 videos and 1 audio, all the same length, playing in VR.
The 4 videos are different camera angles i can skip trough while playing in VR.
When i change to the next video i got a little delay (6k source file) and audio becomes unsynchron.
The next video starts at the time the other video was closed.
How can i archive, that when i switch to the next video, it starts playing at the exact time the audio is currently at?
I imagine i can get a time from the audio and set it as time for the seek node, but dont know how to do it.

Thanks for any help.
