Issue appeared after switching from alsa to 
wireplumber
pipewire
pipewire-pulse

i am not entirely sure if this is an issue with the applet. however i only observe one device in the audio section of system settings as expected.

Audio in system settings shows only one device, while applet shows a device for each reconnect.
i have only been able to test with sony WH-1000XM5 using void-linux

STEPS TO REPRODUCE
1. using paired headset, power on headset and wait for automatic connection. 
2. after connection has been established and device is shown in applet, power off headset
3. power on headset, wait for reconnect, close and open applet, it should then show 2 devices.

OBSERVED RESULT
duplicate devices are shown
media keys can only change between  e.g. 29% and 39% volume and have no effect on actual volume
changing the volume of the last(bottom) device in the list changes the volume of the device.

EXPECTED RESULT
only active devices are shown.
