- Plug in usb headphones
- Open the settings
- select 'sound'
- observe 'output device'
- attempt 'test' - notice no sound on 'output device'
- attempt 'test' - notice sound on system speakers
- switch output device to system speakers - no change
- switch output device to usb headphones - 'test' sound is now on usb headphones

I have two actual audio devices plugged in: 1. speaker under my monitor plugged into the 3.5mm headphone jack, 2. a set of USB headphones.
The 'Sound' settings panel shows three devices:
- Headphones - built in audio
- Digital output (s/pdif) - Jambra UC Voice 750 MS
- Headphones - Jambra UC Voice 750 MS
(I don't really know what 2 is - I usually ignore it)
Normally, after plugging the headphones in, it has 3 selected, but the 'Test' button still plays through 1.
I have to change the 'output device' to 1, then back to 3 in order to make it work on 3.
So, this bug is that the control centre does not reflect reality when you launch it. It looks like it is automatically selecting the headphones just plugged in, but it hasn't actually changed.
