· I have three WiiM sound speakers in my dining room and one WiiM Ultra in the living room. I use them in combination with Roon, where the three speakers and the Ultra are grouped together.
When I use the remote to change the volume, it only affects the paired speaker, not the entire group. I have the same problem with the volume knob on the Ultra. However, other functions like play/pause and skipping to the next song work correctly for the whole group.
I tried 2 scenarios:
1. In the WiiM app, the speakers and the Ultra are not grouped. In Roon, I grouped the speakers and the Ultra into one zone. Music plays fine (via RAAT). The Ultra’s knob and the remote control only adjust the Ultra’s volume. Play/pause and next track do work for the entire group. 2. In the WiiM app, the speakers and the Ultra are grouped, with the Ultra as the leader. I did not create a group in Roon. Roon sends music (via RAAT) to the Ultra. Only the Ultra plays music; there’s no sound coming from the WiiM Sound speakers. The Ultra’s knob and the remote control adjust only the Ultra’s volume. Play/pause and next track also work on the Ultra.
How can I fix this so that the volume control applies to all speakers/ultra in the group?
I think the next step here is to enable some diagnostics on your account so our technical staff can get some more insight into what’s going on here.
However, before I enable this feature, I’d like to ask for your help ensuring we gather the right information.
First, can you please reproduce the issue once more and note the time at which the error occurs. Then respond here with that time, and I’ll make sure we review the diagnostics related to that timestamp.
I just reproduced the issue on January 30th at 07:28 (CET).
Music is playing on all speakers, but when I use the remote to increase the volume, this only affects 1 speaker. I cannot get grouped volume control to work.
Unfortunately, there is no current way today to make the Ultra’s knob or WiiM remote control the volume of a Roon group. They can only control the local device they’re physically paired with. Hardware volume controls are local-only
That’s why play/pause and track skip work (those are transport commands), but volume does not. If Roon is in charge (RAAT playback), the WiiM app grouping is ignored. If WiiM grouping is in charge, Roon can only see/control the leader.
Roon, in turn, does not accept external hardware volume changes as group-level volume events.
So your two test scenarios behaved exactly as expected. Why play/pause does work:
Transport controls (play/pause/skip) are:
zone-level commands
accepted by Roon from RAAT endpoints
Volume is different:
Roon treats each endpoint’s volume as discrete
Group volume is calculated inside Roon
External devices can’t override it
The most reliable setup would be to control volume in Roon only.
Ungroup everything in the WiiM app
Group all devices only in Roon
Set each WiiM device to:
Device Volume (not Fixed)
Then use Roon app to adjust volume.
Let me know if this makes sense, and you do have my apologies here!
Is there a way for me to submit a feature request?
It seems to me that having grouped volume control for three WiiM sound speakers (of the same brand and model) in an open-plan area (two in the dining room, one in the kitchen) using the provided remote should be a fundamental feature.
I would suggest a feature toggle that allows the Roon user to select whether the volume controls affect only the local speaker or the entire group.
