Further to my original post, bought a bluetooth usb dongle and it works with my laptop (acer travelmate5330) but doesn't work with the one it needs to (acer extensa 5620Z).
The headset connects and is recognised. When checking the audio settings, recording and playback is routed through the headset but it actually isn't??!??!?!?!
It works with my laptop with no issues, just a straight install from the cd provided with the dongle then pair up the headset and its done automatically.
So....as you can imagine, I'm at a complete loss! Any ideas ppl?????
(The dongle is a Belkin Bluetooth adapter with Bluetooth v2.1 + EDR)
