And unfortunately i hear no sound recorded ?

OK, … an easier way to get mixer settings is to type:
amixer > mixer-settings.txtand open mixer-setting.txt with a text editor.

Are you using an integrated mic? Or an external mic? Have you tried the “Mic” setting as opposed to the “Front Mic” setting?

its an external headphone mic hooked to the jacks.
thanks for the shorter cmd.

the output:

Yep, its working now, though noisy ! thanks man, once again !

I was just wondering maybe you should post a smart guide command manual, as these small commands are pretty helpful, rather than the GUI !!

Glad to read its working.

Take a snapshot of your settings, so you can go back again in case you forget the working settings. Then move down the capture levels. You should be able to tune out a lot of the noise.

That is a good idea.

I’ve pondered updating the audio troubleshooting guide that I wrote, with a Link to testing mics: SDB:AudioTroubleshooting - openSUSE
