Restarting another topic as it is suggested this might be another problem.
Core: small Xeon server, Roon 1.8 build 850
Remote: iPhone 13, Roon 1.8 build 831
Audio Device: HiFiBerryOS, HiFiBerry Digi+ Pro sending SPDIF to external DAC. Zone is set as fixed volume.
Library: NAS and Qobuz
I do not use Roon app to play music through iphone (not even sure if this is possible), I am using it only as a remote control for the system above.
- I have bluetooth paired headphones on iPhone.
- Roon and (as an example) youtube app is closed and they are not in the background.
- I start youtube and play a video and put it to background. Audio continues playing.
- I open Roon app, the audio (on my bt headphone) stops.
- I do not do anything on Roon, just go back to youtube (i.e. put youtube to foreground). Touch play button on youtube and video starts playing. I do not hear anything because the volume is set to zero.
To eliminate youtube factor, I tried same with Spotify and it exactly works as I described above for youtube. So my understanding is that the Roon app when started, stops the background media playback on iPhone, and sets the volume to zero. Neither stopping the media playback (when the zone is not iPhone) nor setting the volume to zero is what I expect.
