Hi there, When using Roon remote on iphone to control volume of homepod mini using volume buttons on side of phone, after screen locking both volume up and volume down reduce volume. workaround is to close the app and restart.
I’m re-opening the thread based on your message that this issue still occurs. Can you please let us know the exact local time + date + track playing when you are able to reproduce the issue again? We’ll take a look over the fresh diagnostics, thanks!
Replicated the issue on April 20th at 7:49pm MST. Curiously this time both up and down on the volume controls were reducing the volume rather than increasing - I seem to recall it doing the opposite.
Also, attempting to adjust the volume in Roon was resulting in simultaneous control of the ringer control of the phone.
If already disabled, enable it then force close the app. Now open the app and disable it, then force close the app again. Now open the app, play music to the HomePod. Lock your screen, try the volume buttons.
If it still happens, this will need Roon’s input. Do you have another iOS device to try in a process of eliminating your iPhone.
I also note you’re running iOS 18 Beta 3. This could be a factor even if it was on iOS 17.
