I have a normal PC headset with separate 3.5mm plug for mic but this doesn't seem to work with the Pandora headphone jack, sadly.
here my current terminal output results for testing the internal Pandora microphone:
Code:
fusion-pandora:~$ arecord -f cd -D hw:0,1 | aplay
Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

no clue what it means, the underrun message seems to be new I guess.
