> in any case I noticed that the noise background  is very much correlated between R and L; would it be possible to write an alsa-plugin to mix the two channels with an inversion to mix away the noise? It sounds fairly simple, but I couldn't find any documentation on how to make a plugin

 ok, for that I used the route plugin, I must say it's working remarkably well! no more noise from the internal mic.
Still, no noise also with a working mic would be great, so my offer to work on it is still standing.
