I have the following laptop https://support.hp.com/us-en/product/omen-
by-hp-17-cb0000-laptop-pc/26122176/document/c06411586
I cannot make the internal microphone to work. Sound->Input device gives
no device list. Jack plug (pink) mic works.
(The link says: HP Wide Vision HD Camera with integrated dual array
digital microphone. So I guess this is the one and only internal
microphone.)
cat /proc/asound/card0/codec* | grep Codec Codec: Realtek ALC285
cat /proc/asound/card1/codec* | grep Codec Codec: Nvidia GPU 92 HDMI/DP
I guess the internal microphone is related to this "Realtek ALC285"
codec.
In alsa-base.conf I had to add "options snd-hda-intel dmic_detect=0" or
otherwise my screen freezes soon after boot.
I tried "options snd-hda-intel model=laptop-amic" and "model=laptop-
dmic" and "model=auto". The "model=laptop-dmic" shows the device in
"Sound->Input device" but it loops laptop's sound output into the input.
