If this doesn't help, just click around randomly. Maybe you'll find the magic checkbox that makes the noise go away and the voice stay :)
No luck yet, played with the internal mic, which is very noise and SNR is much too high to be usable. Setting vref to 50 gives the best SNR, still not usable though.
Changing the "digital" capture level in alsamixer changes the level of the internal mic signal - is this expected? I looked for the "digital" capture level control in HDAAnalyzer, but couldn't find it - vendor defined?
