Most probably "capture" is not activated for the relevant mixer control. (Yes, that is confusing about ALSA, unfortunately.) With this kind of problem I have always been most successful with a trial-and-error approach using "alsamixer". If you run this application you will get access to all mixer controls in a curses-based interface. You can switch between the "Playback" and the "Capture" controls by pressing TAB. You can then select controls with CURSOR LEFT/RIGHT, change volume or amplification levels with CURSOR UP/DOWN, and activate capture by pressing SPACE. Then it will be a matter of finding the right control(s) to set "CAPTUR" on, and to set volume/amp levels correctly. The relevant control might be called "Mic" or "Mix" or "Aux" or something like that. If you get stuck then you can post the output of amixer | egrep -i '^( .*capture|[^ ])' and we might be able to give more specific advice. Also tell us which application you use to do the recording. -- Regards, | http://users.icfo.es/Florian.Kulzer Florian | -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
