I can not see people communicating with me in direct communication text and I can't hear them talking to me over direct communication voice. A solution that was recommended to me was to activate my microphone even if I wasn't going to use it.

I have a laptop with a built in microphone that was damaged and does not currently register within my windows environment and as a result I cannot enable one.

As a result, it is my belief that other people who have disabled microphones (for whatever reason) are unable to see others direct chat and text communications.
