Triumph is ours! My internal mic is working and can record audio. It's
like a have an actual laptop without having to lug around another mic!
Hooray
I found two files in /etc/modprobe.d that were turning off the
dmic_detect.
➜ egrep -r dmic /etc/modprobe.d
Looking at this: https://bugzilla.kernel.org/show_bug.cgi?id=205959 i tried
editing the
/etc/modprobe.d/alsa.conf to have the option... restarted... same output
** Attachment added: "alsa.conf_options"
hmm... it says that same message here
snd-intel-dspcfg.dsp_driver=1 is set in the command line. But later on
it says i should pass that option.
** Attachment added: "with_dspcfg.dsp_driver=1"
Maybe it's the "HP Wide Vision FHD Camera" which should be treated as a
camera and microphone? i see it register with uvcvideo in both.

OK, Let's see if this helps you narrow it down. This file is with
dmic_setting=0 removed from the grub cmdline

Thanks... that at least lets them show up in gnome.. but my internal
audio array isn't an option. If i plugin an analog mic it works though.
Just the realtek audio array doesn't work
