Volume controls in pebble music app don't work

abranson opened this issue 9 years ago · comments

When using the stock Sailfish music player, the volume controls on the pebble have no effect. The play/pause and skip controls work.

This is because stock music player does not have volume control.

why not change the system volume?

Because it is system volume and affects not only music.

To be clear - volume control via MPRIS2 is already implemented. It is up to the current MPRIS2 interface owner (usually music player) to react somehow when it gets vol-up/vol-down request.

So your expected resolution to this would be that Jolla implement volume control in their media player, probably by passing it on to the system volume? Are there any media players you know of that do this already? I have Daedalus installed, but although that seems to have MPRIS implemented, it doesn't work with the pebble at all.

You are pretty much spot on regarding how to solve the issue.

Thanks, that's very interesting, though seems to be more concerned with external devices such as carkits which do not have their own daemons running on the phone. Apparently it is currently possible to control the system volume via DBus, but only through the org.PulseAudio.Core1.Device interface, which would be a pragmatic alternative, not to mention extremely useful.

After all, the current code may be cleaner, but the current situation justifies a workaround which wouldn't be particularly messy.
Maybe a config option in the pebble app to 'Control system volume' that switches between the DBus calls might be less filthy?

I am reluctant to implementing global volume changing by controls clearly dedicated to music. I imagine someone being very surprised/annoyed on a missed phone call because of low ringer volume, just because one turned the music quiet.

I just tested the music app on my android tablet, and the volume buttons alter the system volume on there. I tested MX Player and Google Play Music. There was also a progress bar under the track name showing the track position.

The system volume is independent of the ringtone volume.
