Sometime a need comes to test microphone for use with VOIP applications such us Skype. The simplest and easiest way to test microphone ( MIC ) on your linux system is to use default alsa tools which come with alsa sound system package. First we need to check if alsa had recognized and our sound device.

You made a mistake at the last.
arecord hw:1,0 -d 10 /tmp/test-mic.wav

should be
arecord -D hw:1,0 -d 10 /tmp/test-mic.wav
