How can I increase microphone gain (dB) ??

Discussion created by Frank Chen on Aug 17, 2011

We have received SABRE(MCIMX53SMD). I recorded my voice from recorder app is too low. How can I adjust dB value? What command that I need using it(( for example "alsa_amixer sset 'MIC GAIN' 20dB " ) ?  Thank you
