Suppose you reboot the machine without changing the hardware.
Does each device always retain its card number across the reboot?
In my case no. Consequently I can reboot and find that the
VoIP ring is being sent to the headset. Not acceptable.
A persistent name remains associated with a specific device
across a reboot.
