ML/NL converter - sync both directions

Thanks to many of you on this forum, I have succesfully set up a ML/NL converter to get my BV7 ready for NL multi-room.

My setup includes a BV7 via ML/NL and an A9.

I'm opening up a new thread as there remains one issue that may be interesting to the broader group.

what works is to play audio from the A9 in sync to the BV7 (deezer, tune-in, dlna).

However, there is quite a delay when trying to send the audio signal from the BV7 to the A9.

any ideas whether this can be solved?

Thanks. I am not sure whether this will be helpful. Once I install it my video and audio would be out of sync on the BV7? Let me reply to the other thread.
