I would like to think that my programming skills arent too bad :-). Even
so, I am inclined to look for a README.install of some sort before I
spend hours/days looking through someone else's source. I have been a
linux users for almost 10 years and just wrote a linux-driver for a
PCMCIA audio/DSP card from www.cac-dsp.com (their Bullet2/33 cards). I
learnt very quickly that a 40 line README.install file packaged with the
source would save me more time than to answer all the questions that
would invariably arise from someone trying to use my code.

I havent tried out Jack. Havent had a need to so far....guess I will
have to start to make use of my $1000 investment...

The alsa-projects website has a few lines
hinting at the use of amixer....but its minimalistic :-)
