Clipping in my webcam mic?

I just tried to record a little video of myself playing and i ran into trouble. No matter how low i turn the recording volume when i play and sing with my ukulele i get these nasty clipping and distortion when i hit the strings just a little bit harder. I have a logitech quickcam pro 9000 and it sounds quite good when i record with it (voice) and the video seems also ok.
Does someone have a tip for me there?

I hope this is the right forum as it isnt really a problem with the ukulele no? anyway, any ideas are appreciated.

i made a little video showing what happens-> video clipclip

Maybe windows turned on the micboost... if it did, turn it off at the sound settings (you'll find them in your taskbar on the lower right bottom, it's a little speaker symbol) and in there at the "microphone" setting.

Hey that was quick, thanks for the idea, but the cam has a seperate recording level and i turned off the boosts in there already i am afraid

What software are you using to record? Perhaps it has its own audio gain. Try recording something with the Windows sound recorder.

I take it you have tried the Audio Tuning Wizard that comes with the webcam?

Maybe there's something here that will help.

You can also try simply reducing the mic input level.
