This is already possible - using the hw.snd.default_unit sysctl (changes what /dev/mixer et al do). That is what I was thinking - basically you watch for new sound devices and decide which one to use (or sound events to say something is plugged in) and set the sysctl accordingly. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
