     122The Linux kernel does not guarantee the enumeration order of devices but at the user space level you can use systemd with udev rules to name devices in a persistent way. It can happen that devices are moving around or flip flopping between boots.

     124Take a look at /sys/class/sound/ to see if the two audio devices (GW16157 and other device) are getting different indexes. If that is the case you can use 'udevadm info /sys/class/sound/<device>' to look at the udev environment for the various devices and come up with something in /etc/udev/rules.d to rename the devices when they enumerate (see /lib/udev/rules.d for examples).
