Still doesn't work for me.
I've checked the sound setting: It's on analog stereo duplex
I've installed pulse audio volume control: Everything on 100%. Still a much too quiet micro.
I've removed pulse audio and used only the alsamixer. Still quiet. If I set the amplification to 40db my speech is loud enough to hear (although still a bit quiet) but there is to much noise to use it for something.
Any other ideas?
I'm starting to become desperate
