Multiroom sync off

Hi,

I noticed that since the latest 3.6xx update my sync in multiroom is quite off.
I tried adjusting the settings, nothing helps.
This wasn’t an issue before.

Master :
Rpi 4 8gb ram
Hifiberry DAC
Hifiberry Amp60

Slave :
Rpi 4 8gb ram
Pimeroni dac

Both running on 3.617 (latest stable)
