Description Andrey Kozlovskiy 2020-09-03 14:41:38 UTC

For some reason I need to double press the start/stop button on my bluetooth headset to pause or resume media playback, for example if I am using Elisa or if I am playing some video in Firefox with plasma-integration plugin enabled.
My bluetooth headset is Sony WI-C400, I use Kubuntu 20.04.1 LTS. 
Can anybody confirm this problem? Maybe it depends on the headset, or maybe this should be fixed upstream?

Can I have output of

"xev" when you press the button
"dbus-monitor" when you press the button

(please check the latter for sensitive information before uploading it)

Comment 4 Andrey Kozlovskiy 2020-09-03 16:37:24 UTC

Attached output of xev and dbus-monitor commands.
I also marked the the moments of presses: you can search for 'First press', 'Second press', 'Third press', 'Fourth press' framed with # symbols.
dbus-monitor does not display anything on intermediate presses (presses after which nothing happens).

Actually, sometimes dbus-monitor has an output on intermediate presses, see the attachment.

Requested info provided.

Comment 8 Andrey Kozlovskiy 2020-10-31 17:25:25 UTC

This is still an issue in Kubuntu 20.10 (Plasma 5.19.5).
On the other hand, Ubuntu 20.10 (Gnome 3.38) works fine with the same headset - single press to start/stop playback as it should be.
