I have an IC-705 and an IC-7300 and they both use the same TI Audio Codec chip. This chip does not seem to have a serial number and ICOM do not provide the serial number of the rig for the audio codec. I have been unable to find a way to distinguish them when trying to create a fool-proof means of identifying them that will survive a re-boot of my debian 12 computer.
All I can see is the physical port number in the form:
/dev/snd/by-path/pci-0000:00:14.0-usb-0:1.4:1.0 and ..../pci-0000:00:14.0-usb-0:3.4:1.0
Unless I move the USB connectors around will these always remain the same after a reboot?
Is there any other means of distinguishing between the two devices?
