I'm not sure how 'recommended' it is, but there is a method of running 
scripts when devices are plugged in using udev rules.  There is a guide 
here 
http://www.banquise.org/hardware/how-to-automatically-run-a-script-after-inserting-a-usb-device-on-ubuntu/ 
though it involves being able to identify which device your usb sound 
device is.

(Rather than blindingly following the example I recommend reading 
through http://www.reactivated.net/writing_udev_rules.html to understand 
what you are doing)
