[LAD] Opening ALSA devices (hardware and PCM)

Hello Clemens!
   the asterisk logs only show, that it can't open the device. I tried to put 
in some extra debug info, but it simply likes to fail with pcm_open.
   Still from what Fons said, I've given up the ALSA jack_plug as a bad job and 
would like to concentrate instead on the JACK application of Asterisk 
(app_jack).
   Oh before I forget: In some cases Asterisk opened the device and happily 
crashed afterwards, printing something about segfaulting, while somewhere in 
libc. Not of any use to me. If you'd like to know - I know that there are 
people, who use chan_alsa and would be delighted to see something fixed - I'd 
rerun the tests and figure out where what happens and send you the chan_alsa 
chan_console messages in question. I guess the crash issue is something for 
the Asterisk people only. Since a crash is a very bad thing, not the best 
display of reliability and stability. :-)
   Thanks for your answer and for taking the time to look into chan_alsa. This 
was very kind of you!
   Warm regards
          Julien
