However, the switch originally to Mic 2 was _heavily_ advocated by
Jöerg. Also, the linked talk page
http://wiki.openmoko.org/wiki/Talk:Neo_Freerunner_audio_subsystem has
quite a dispute about the issue going on.

All in all, it sounds like routing through either of the PGAs is a
wrong approach to fix the problems, it just happens to decrease the
amplification. I think additional information, even though only for
your specific case again, could be had if you kept that setting at Mic
2, but a) reduced Mono Sidetone Playback Volume (control.12) from 7 to
5 - does it help? or if needed b) reduced Mono Playback Volume
(control.5) from the default setting.

I sometimes feel there is no end to this discussion. Jöerg's second
attempt and "one true" statefile,
http://docs.openmoko.org/trac/attachment/ticket/2121/gsmhandset.state.new
was quite undisputed, but I'm not sure if the mono sidetone playback
volume setting of 7 is indeed now the +6dB affecting setting that
should be changed.

And always it should be remembered that these vary between A5/A6/A7,
buzz-fixed and non-buzzfixed. For me buzz-fixed A5 the
gsmhandset.state.new seems fine, but I think the baseline should be
according to A7 (which should be equal to buzz-fixed A6 in this
aspect).
