Is there a microphone that works with Mindstorms EV3? I'm planning to program my EV3 robot to do voice chat over VOIP using ev3dev and a Debian program. Is this possible? Are there microphones known to work with EV3, and has anyone had experience using them?
Sadly, there isn't much info yet.

Current options for audio are:


USB Sound Card
BlueZ 4/Pulseaudio 4 (BlueZ 5/Pulseaudio 5 supports
A2DP only)


The number of devices that have been tested and documented is extremely limited, but at least one has been confirmed to work. The non-bluetooth solutions that have been tested successfully are the following. 

Tested and confirmed adapter chipsets:


C-Media Electronics chipsets (Example)


Tested and confirmed microphones:


Logitech C170 webcam built-in microphone
