On the current version of Mac OS X, every sound device has a unique "device UID" that identifies the specific location of the device in the USB tree, Firewire port, or the built-in audio location of the sound card. This unique ID is therefore persistent not just across sleep/wakeup cycles, but also through reboots. You identify a sound card once (e.g., plugging and unplugging it) and it is good "forever." An example of a device UID on Mac OS X is "AppleUSBAudioEngine:microHAM:microHAM CODEC:fa222200:2,1" Windows must have the same thing. In both OS, you are however at the mercy of the software author whether he has implemented this level of detail :-). 73 Chen, W7AY ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
