I have searched under plantronics nut the results were not helpful, so Im making a post.
I use Skype and TS and Vent with out any issues, so I know the unit works fine.
BUT, when I try to use Mumble it just will not recognize that there is a wireless headset /dongle there. It installs fine, and works fine, i can hear others speaking, but thats it.
Can anyone help me?
After much reading and trial and error I found out how.
In playback devices right click on the headset.
Set to 16bit (Tape Recorder Quality).
Once I did this i could use both Mumble and Teamspeak and hear and speak via the headsets.
Once i had used the drop down box to change the 16bit quality it became grayed out, but i meant I can now use the headsets. This fixed it for me.
