Audio applet with many spurious audo devices

SUMMARY
***
The audio applets shows a long list of input and output devices, when really there are only 2. Moreover the list of devices is not updated when the USB-C dock is unplugged.
***


STEPS TO REPRODUCE
1. Plug-in USB-C dock with HDMI monitor and sound output
2. Compare output of `pactl list sinks short` and the list in the audio applet
3. 

OBSERVED RESULT

`pactl` or `pavucontrol` only report the existing output and input devices (1 or 2 in my case). The audio applet shows a very long list of devices (see picture), which seem to be the same devices repeated over and over.

Result of `pactl sinks list short`:

2792    alsa_output.pci-0000_00_1f.3.hdmi-stereo        PipeWire        s32le 2ch 48000Hz       RUNNING



EXPECTED RESULT

The audio applet should show the same devices as `pactl`.
