Volume control multiroom Bug for Up2Stream pro v3 on newest firmware

Hi,
i have a multiroom issue for the Up2stream Pro V3 with the newest firmware 4.6.415145.35. App is also in newest Version. Both Up2stream Pro V3 have Default settings.

I have two Up2stream Pro V3 . One has the spdif out extension Board connected and the other one has the DAC Extension Board and the volume control knob connected.

If i connect them in multiroom mode, the one with the DAC has a defect volume control. If the Volume is off, both audio output are silence but If i raise the volume a bit (for both or single up2stream pro v3), the Up2stream with the DAC outputs 100% volume. The other one works as expected and has a regulated volume.

In normal mode (no mutliroom) everything works fine on both.

For me i cannot use them in mutliroom mode at the moment. Maybe this is already a known issue for the newest firmware? Also tried to restore factory settings. But this did not help.

Here are the internal informations:

I have the same problem. If I remember correctly, if you change the "master’ it will work correctly. Still sucks.

Would bei nice If the master volume works for both. But with my configuration even a little slide with the master volume gives full output for the one with the DAC…

I am a bit sad about the support. I still got no response in any channel from arylic. EOL for product?
