I agree on the lack of support for people with disabilities.
I have the same issue for the same reason.
About a year and a half ago I lost complete function of my left ear.
Interesting that in reading the thread the others also point out SSD [single sided deafness ] on the left side.
Based on what has been described here and my checking of the system settings on the multiple computers I use, I will be looking for the adapter myself.
Question – does anyone know if an adapter exists that supports using a headset that has a mic and converts stereo to mono?
-> Single 3.5 plug <-
The computer has a single combined plug for mic and sound.
I use the headset for Lync conversations / meetings and mic as well.
Then the headset for general listening for other needs where it is ‘hear’ only.
