    capture in connection

    Hi,

    the problem is the connection of the capture bus. You must connect the capture in of the codec to the mic input. This one can be done with a control aplication or command. I have controled this connection with alsactl tool.

    good look

    Hi Skolima,

    you must have installed alsa-utils extra packages. After you can use the alsamixer, amixer and alsactl utilities for your audio configuration. Take care with the capture settings if you want recording with your mic. P.e you can control this configuration with amixer command, alsamixer gui utilities or alsactl command too.

    you have information about this utilites in
    http://alsa-project.org/ -> http://alsa.opensrc.org/ ->http://www.alsa-project.org/~valenty...ini-HOWTO.html

    and with the shell manuals
    man amixer ; man alsamixer ; man alsactl

    Regards
    Candido
