hi David, the fw patch's not working confuses me. It seems weird.

I believe the fw file must have been loaded.
Evidence 1:
    $ dmesg
    ...
    [ 9.210061] ALSA hda_intel.c:2650: Applying patch firmware 'optiplex-380-patch.snd-hda-intel.fw'
    [ 9.210123] HDA Intel 0000:00:1b.0: firmware: requesting optiplex-380-patch.snd-hda-intel.fw
    ...

Evidence 2:
    $ cat /sys/class/sound/hwC0D0/init_verbs
    ...
    0x1a 0x701 0x0000
    0x1b 0x701 0x0000
    ...
    These lines can also been found in alsa-info.sh result.

I don't get it: everything seems ok but no sound. There must be something important I ignored ...
