WiiM Amp Pro : no Audio Sync for multiroom / groups

[taps]

How can one add delay to the WiiM Amp Pro to sync grouped players ?
There is a setting for WiiM Pro (Device Settings > Sync Audio > Audio Sync.) , but it seems to be missing from the WiiM Amp.
In my setup, the WiiM Amp produces the sound a bit sooner than the grouped WiiM Pro.

You're right! (But you already knew that.)
It's missing from the amp's menu, no matter whether the amp is the group parent or not.
Can't you advance the pro via its sync enough though?

Please create a group with Pro as the parent device and run auto-sync on Pro. Then create a group with Amp Pro as the parent device and check if it is synchronized.

It may be possible to perform automatic synchronization on the child device side, but it may not work.
