I actually have pulseaudio running (and plan to keep it since Debian has it by default). It seems mixer names changed a lot between Maemo kernel and 3.19. I have parser for alsaped.conf, but was not able to identify matching mixers.

HPCOM? Mono? In schematics, earphone is connected to Left HP, channel B (loudspeakers are channel A). But even after enabling all its controls, earphone stays muted. My N900 may have broken flex causing my touchscreen problems too.
