I have a Conexant High Definition SmartAudio 221 device in my Compaq Presario CQ-60 211DX, and I want to record a Cyberacoustics headset through it via a standard 3.5mm jack. When I do this normally, in Audacity, it's wonderful, with stereo sound and great volume/quality. Unfortunately if I have any type of sound playing through the speakers at the same time, the recording audio gets extremely quiet/unsensitive and you can mostly hear garbled up noises that seem to be my voiced mixed with whatever is coming out of the speakers. I have experienced this also with the default sound recorded in Windows 7, and in Linux, so I believe it is a sound card issue.

My guess is I need to configure it so it will keep the signals straight, but I honestly have no idea how. Could, someone please point me in the right direction here?

Thanks in advance! :)

I am assuming it is a notebook you're talking about? Did you check if the internal microphone gets disabled when you plug in the external one? – tH0r Jan 14 '13 at 22:01
@tH0r Yes, it is a notebook. I don't know if the internal mic gets disabled or not. How would I check that? :) – Miguel Jan 16 '13 at 4:55
@Miguel - Have you checked to make sure there's no noise cancellation active, in the drivers or sound control panel? – Jeeva Jan 18 '13 at 13:57

Try the steps on the following webpage: Compaq Support : the part about the default microphone may be interesting for you.

Or about directly muting the internal microphone: Disable Int. Mic

If that doesn't help try this article about: Driver Problems (and check if the steps above work now).
