Bug ID: 502501
Summary: Media Key usage blocked by bluetooth headphones
Classification: Plasma
Product: plasma-mediacenter
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: MediaController
Assignee: ksi...@gmail.com
Reporter: w...@savethevowels.org
Target Milestone: ---
SUMMARY
For some (but not all) bluetooth headphones (I've observed this with Sennheiser
Momentum 4, but not Sony XM5s), upon connection, a second 'Media Player' is
created with the name of the Bluetooth headphone. This shows nothing playing
and appears to have no use, hitting the buttons does nothing, but after a short
time, this becomes the default media player, and absorbs the media control
hotkeys which would otherwise be directed at the running media playback app
(e.g. cmus).
In these cases, the media playback continues fine, and on-device controls
control the media playback just fine (e.g. tap the earcup to pause, swipe
forward to change track). But all keyboard media controls are eaten by this
phantom device until it is disconnected and reconnected.
This may be difficult to address device-specifically, as not all bluetooth
headphones create this device, but another way to address this would be to
allow us to give priority to a certain media playback for control with media
keys, or to 'disable' a media player.
I am very happy to run any commands you'd like to provide output which
addresses this, understanding that not everybody has these particular
headphones.
STEPS TO REPRODUCE
1. Connect offending headphones (e.g. Sennheiser Momentum 4) via Bluetooth.
Codec doesn't appear to matter
2. Observe the creation of a second 'Media Player' entry for the headphones
which is unresponsive to control.
3. Play music with a music player which accepts media controls (e.g. cmus)
4. Attempt to control using keyboard media playback keys (e.g. play/pause, next
track)
OBSERVED RESULT
Immediately after connection, generally this works as expected, allowing you to
use the media keys. However, after an unclear amount of time, media keys stop
working, seemingly directed to this phantom media player.
EXPECTED RESULT
Media keys on keyboard work as expected.
