Re: quattro multi plugin.

[Patrick Shirkey <pshirkey@boosthardware.com>]

This is wierd. Using the exact same commands I cannot get jackd to load 
now. The card still, ahem, works, cough, with a single pcm device.

1068 waiting for signals
creating alsa driver ... q4|1024|2|48000|swmon
ALSA: no playback configurations available
ALSA: cannot configure capture channel
cannot load driver module alsa
jack main caught signal 15

This is after a reboot due to jackd hanging the machine after 
accidentally loading the hw plugin after having semi success with the 
code below.
