Raspberry pi 4 not save the modifications

Hi guys,

I've got a raspberry pi 4 with a DAC allo piano 2.1 and Libreelec 9.2.

I copy the firmware files in /lib/firmware but if I reboot the FS it's restored at default.

What is the procedure for save the FS?

Tank You and sorry for my little english.

Quote from HiassofT

/lib/firmware is a volatile directory in a ramdisk and re-created on every boot.

If you want to permanently add firmware files create a /storage/.config/firmware/ directory and put the files there, then reboot.

so long,

Great HiassofT, it's work.

I use this firmware to filtering subwoofer output:
