I am having a similar problem where I can hear myself when I speak on the mic, but when I do the samre thing in KRec, and it dosent seem to pick anything else. It semms that the problem is that I can't record myself when I try SKYPE. Could someone please shed some light for the noob here??

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

Could you please, pleease provide more information about what actually did you do to get this to work? Any links, docs, etc?

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
