Comment 31 for bug 1840725

Reproduced on `Acer Aspire VN7-592G`. Runnung on Ubuntu 19.10, kernel version 5.3.

Firstly had no sound devices detected at all. Adding
`options snd-hda-intel dmic_detect=0` to `/etc/modprobe.d/alsa-base.conf`
Fixed the issue and sound appeared.

But after that found out, that no input sound device is detected by system, along with headset mic.
adding
`options snd-hda-intel mode=aspire-headset-mic`
resolved issue for headset, obviously, but still no default input device is detected by system.

Also've been trying to use
`options snd-hda-intel index=0 model=laptop-dmic`
after that. Device appeared in sound panel, but it's recording only static noise, nothing more.

Still finding a way to resolve issue for built-in mic.
