After a while I found that some of the audio devices in the "audio volume"
widget are duplicated, and trying to change the volume using my keyboard knob
result in the volume level being stuck between two values (e.g. 68% and 72%).

I found that this problem also arise when right-clicking on a device and
changing its profile, resulting in the same symptoms.

After some tests, it seems:
- The volume being stuck is linked to the fact that it is trying to change the
volume of the old profile device, and that one has its volume fixed to its last
value (even trying to change the volume using the volume slider does not work)
- The volume on the new profile device can be changed
  - And when selecting the new profile device, the keyboard knob works

I update my system regularly and I would say that this problem appeared about a
week ago.

STEPS TO REPRODUCE
1. Click on the audio icon on the bottom right
2. Right-click on the currently selected playback audio device
3. Change the profile

OBSERVED RESULT
The audio device(s) of the newly selected profile have appeared, but the one(s)
from the old profile still remains in the list.
Trying to change the volume of the old profile device is not possible (keyboard
knob or volume slider).

EXPECTED RESULT
When changing the audio device profile, the old profile device(s) should be
removed from the list, and the currently selected audio device should be set to
one of the new profile devices.
