The client ID depends on the sound card number. ALSA drivers grab the
first free sound card number when they're loaded unless told
otherwise, so the client ID will change if drivers are loaded in a
In your /etc/modprobe.conf (or whatever your distribution uses), add
"index" options to your drivers to force them to always have the same
options snd-whatever index=0
options snd-usb-audio index=1
If a driver handles more than one card, use multiple index values like
options snd-usb-audio index=1,2,5
