sorry to jump in so clumsily, but i highly agree in every point. why
make it intentionally user_un_friendly?
i don't want to start a geek vs. everyday user discussion (again, i had
enough of those in #alsa), but i very much vote for 'pragmatic' defaults
in general. i can't help it but 2ch s16le 44100Hz just _is_ the most
used format.
