How to operate the microphone ?

[Faruk]

Hello

I struggle for work the microphone. My purpose record voice. I searched on google. Installed alsa-utils, I tried amixer -c 0 cset numid=23 0 command but I took amixer: Cannot find the given element from control hw:0. I tired arecord but My research did not give result. When I tried arecord output.wav command, I took arecord: main:682: audio open error: No such file or directory error How can I work the mic?

Edit: I tried new asound.state file in this site:ftp://staging.olimex.com/Lub-clients/asound.state . Also I use arecord -l command in console result just return this ****List of CAPTURE Hardware Devices ****. I think olinuxino can not find microphone device. Is there any advice?

  Subdevices: 1/1
  Subdevice #0: subdevice #0


this is what you should get, check for this block in script.fex
