I have three systems with the same hardware and software,

in /proc/asound/card0/codec#2

system 1 : Subsystem Id: 0x7fafffdd
system 2 : Subsystem Id: 0xffffffff
system 3 : Subsystem Id: 0xff7f7fa3

Why the "Subsystem Id" is different between the three systems?

Is there a way to don't use it in :

vendor-id subsystem-id address

If I set the right subsystem-id in 
/lib/firmware/forgotten-ezono-hda-settings, the kernel doesn't crash and 
the sound works perfectly.

I need one /lib/firmware/forgotten-ezono-hda-settings for all systems 
and I can not get "Subsystem Id" before loading snd_hda_intel successfully

Any idea please?
