some details you might find useful:
about powersaving of hw-accel:

factoid: all stock media apps use MAFW
http://wiki.maemo.org/Documentation/...amework_(MAFW)
. MAFW has several drawbacks, e.g. no easy way to implement equalizer incl volume control (esp for external audiocard), no gapless playback.
PA and ALSA have a quite strange relationship, when you playback audio to normal PA, data flow is like this:
app -> (PA -- weird plugins - xprot-limiter) -> ALSA card driver
when using 'normal ALSA' (aka "default"):
ALSA -> PA-ALSA-compatibility-plugin -> (PA -- weird plugins - xprot-limiter) -> ALSA card driver HW:0,0
It should be simple to make PA use sth different than hw:0,0 for audio card playback, however that's possibly not what you actually want. It would redirect *everything* to the new audiocard
For automating H-E-N refer to blue_led's scripts in
