Title:
  Sound card not detected on Dell Latitude 9510

Status in alsa-driver package in Ubuntu:
  New

Bug description:
  I am running Ubuntu 20.04.01 LTS, kernel (linux-image-generic) version
  5.4.0.47.50.

  I believe my sound card is not being detected by Ubuntu.  I checked
  the serial number and via BIOS (which I've upgraded to the latest
  version) according to the specs (https://topics-
  cdn.dell.com/pdf/latitude-15-9510-2-in-1-laptop_owners-manual5_en-
  us.pdf) the sound controller/speaker should be Realtek ALC711-CG /
  Realtek ALC1309D.

  However, when I run lspci only the following device appears:
  00:1f.3 Multimedia audio controller [0401]: Intel Corporation Device 
[8086:02c8]

  In alsamixer, only the HDMI port appears.
