Title:
Sound card not detected on Dell Latitude 9510 (Realtek ALC711)
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
I am running Ubuntu 20.04.01 LTS, kernel version 5.6.0-1027-oem
(checked via uname -r).
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.
