Hallo,

Yes, thats
true, you might read Josh's comments about writing the ALSA
part, he surely had a good time.
well i have some idea of that, since JACK has to do basically the same
thing.
ALSA is not really easy to program, and thats not
about novice programmers
and advanced programmers. There are just some people who do not understand
why a Sound API has to be that complicated. (JACK shows that it hasn't to
be this way)
if you look back over the last 2 years of alsa-devel,
you will see why
ALSA is so complex.
What might be needed is a kind of "Good Practice Advice" document for
application developers that use ALSA. I know, you will say that good
practice would be to use Jack or PortAudio :), but still there are
lots of apps that want to use ALSA but fail at simple things. On of
the worst Bad Practices seems to be hard-coded audio device names or
enumerating soundcards. For example mplayer only allows one to specify
hw:0, hw:1 and so on but doesn't do correct format conversions. This
seems to be a fundamental misunderstanding of how ALSA and its
plug-PCM system works. I guess developers write their software this
way, because all the complexity of ALSA overshadows some main points.
