I have a relatively new Samsung Q330 laptop, Windows 7
I recently bought a Plantronics Audio 300 desktop microphone
When I plug in the 3.5mm jack into the microphone slot on the side of the laptop, the computer doesn't locate it separately from the in-built mic (See attached screenshot)
The mic works but there is all sorts of interference and distortion because I presume it is clashing with the inbuilt mic
Maybe Realtek HD Audio Manager is causing problems here but if I uninstall that program or even roll back to an older driver I lose sound altogether
Any idea why this is happening and how to fix it?
