Adjust the volume?
-
I made an app to listen to internet radio. Unfortunately, I can't get the volume control to work. Sliding the slider doesn't change the volume.
My complete project is here.

Sorry i can't help you ! But thank you for this radio app !

my quick and mostly uninformed guess would be that for an app to do something intrusive like changing the sound level for the system, some authorization would (should) be needed.
So maybe tracking what is happening at the D-Bus level by starting 'gdbus monitor' just before initiating the change in your app and looking at the saved result could be a way to confirm (or not) this idea.
If that's the problem, it could be a matter of setting the right Apparmor policy for your app.

Thanks for your suggestion.
I'm not trying to change the system volume. The slider only calls
C++
QMediaPlayer::setVolume()on my own QMediaPlayer instance.
The property changes correctly (I can read back the new value), but the playback volume never changes.
Is QMediaPlayer::setVolume() currently unsupported by the AalMediaPlayer / MediaHub backend on Ubuntu Touch 20.04?

@dl8aax this is something we've recently also noticed, though it might have been the case all along, or possibly since the upgrade to noble.
Do the physical volume buttons work? Does the volume slider under the volume indicator work? If the answer to both is yes, maybe seeing what the volume indicator does.in the code.
