OK, installed everything to do with pulse ....... the sledgehammer approach!
When I did this I had the wireless headset functioning and when I opened the pulse volume control I was able to hear the beep when I clicked on the volume sliders.
The Mic also showed on the volume level when I adjusted the slider.
I was unable to play any sounds either through the speakers or the headset, from any app.
So I rebooted ....... headset no enabled.
Tried again several times, but still no headset.
Still no sounds from anything unfortunately.
Not looking promising .......... now no sounds at all
