Hello,
I've been trying to display track name on bluetooth device AND control a player on computer using
device's buttons.
I can have one, but not both.
If "mpris-proxy" isn't running I get key pressed/released event on computer and I can control
the player
with buttons. Even if player doesn't have GUI it seems to get signals on dbus mpris interface. BUT
no metadata
seems to be send to bluetooth device and there isn't anything on display.
When "mpris-proxy" is running player doesn't get any button events, BUT I have all track
information on
a display.
In both cases, with pulseaudio, "btmon" shows that device sends key pressed/released events:

On bluealsa I only have sound. No keys or information on display.
Is this issue related to pulseaudio?
Can I somehow take over uuid 0x110e using dbus and python and still have sound?
I tried connecting to 0x110e L2CAP socket, but this only works if device is disconnected and unable
to produce sound.
Please advise
