Internal microphone noise

[malkavian]

Hi everyone,

I've notice, that my laptop's microphone produces a lot of noise when recording. I've tried to change settings with alsamixer and here are the results.

There are a few contols related to recording: Capture, Digital, Mic Boost, Internal Mic Boost, etc. When I set Mic Boost on non-zero, microphone produces a lot of noise. But if I set it to zero and Digital to max record is clear, but too quite. May be anyne knows, how to solve this issue? Can I increase maximum limits for Digital channel? Or there are some options in asound can be set?

Thank you!

What happens when you active Capture slider and andvance it to 90% or so?
