Well, if people would tell us what the ID's were rather than bypassing the system then we'd be a lot better off by now. :-) Seriously though, matching by card vendor ID isn't impossible but would be rather messy in the current system as the probe is called for each logical device. An average sound card has three to five "devices" on it. Usually the first one (ldn 0) is the sound device, but sometimes ldn 0 is the card controller, and sometimes other things like the ide port or joystick ports occupy the first slots, pushing the sound part to ldn #3 or 4 or so. The current probes don't have any idea if "this" logical device is the first or the third on a "card".
