Revision history [back]

Currently, it is only possible to adjust the volume via the rockers on the phone, all other controls get ignored. Please add:

1. Headphones/Headsets Volume buttons, it is an industry standard, from what I understood.
2. Bluetooth devices with audio output should control the phones volume: Car stereo systems, speakers, etc. Pay attention to stupid bt devices, which would use the level of the Jolla phone instead using a sane default, so that the bt device does not start up with a Jolla set to 100%. Might be irritating to the listener or damaging to the speaker.
3. Make it possible to use Pebble and other smartwatches to control audio. It can control the played track via MPRIS, dunno what is needed for audio.
4. Add an option to lock the onboard volume rocker, if a device with external audio control is connected, so we can also tackle this "bug": https://together.jolla.com/question/8239/bug-volume-adjustment-works-while-phone-is-locked-independent-of-any-application/

The current situation is annoying, since I always need to adjust to devices in order to produce a nice volume level with external speakers that have their own volume adjustable.

The current situation is annoying, since I always need to adjust to two devices in order to produce a nice volume level with external speakers that have their own volume adjustable.

Update: I found some hints on the internet: http://theheadphonelist.com/wireless-fidelity-making-sense-bluetooth-headphone-technology/#profiles

AVRCP (Audio/Video Remote Control Profile) – provides remote control of media playback (e.g. play/pause and skip/previous track functions); used in conjunction with A2DP. The latest AVRCP versions (1.4 and 1.5) allow direct control of device volume as well. With previous versions, volume controls affected headset volume independently of the connected device.
