Volume 100% when synced

I have 2 speakers with minis. My biggest, loudest speaker… When it’s the master in multi room the volume is either off or wide open. There is no in between. If it’s the secondary device it’s fine. Any ideas?

Freaking love this board!

You’re using MINI V3 + DAC board? If so, it’s a known fault in hardware… you could use the internal DAC.

Yes, the speaker that goes full volume has a DAC. The smaller speaker that works correctly does not. I’m using the DAC expansion board with the mini.
