CP965 doest recognite its own microphone

[EffieB]

Please help! Been trying to fix this all day

Upgraded our CP960 to CP965, cant get the microphone to work. It only recognizes the microphone that is in the computer. 

Any idea how to fix this?

Thanks!

Yealink support said that these models (CP965) had a flaw where randomly the audio would just stop working. No sound. No microphone. You might want to talk with Yealink support.
