Built-in speakers and microphone not working on clean install of Ubuntu 20.04 on Dell Latitude 9510

Asked by Harrison Chen

The microphone and speakers do not appear to be detected by Ubuntu (i.e. only have dummy audio, no microphone in sound settings). The sound card is detected by alsamixer, and also by lspci:

harrison@lassen:~$ lspci -nnk | grep audio
00:1f.3 Multimedia audio controller [0401]: Intel Corporation Device [8086:02c8]

I've tried force reloading alsa, reinstalling alsa and pulseaudio, the suggestions in the troubleshooting post (https://help.ubuntu.com/community/SoundTroubleshootingProcedure), do not have timidity installed (e.g. as in this bug report https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1874465).

Note: I've cross-posted this here:

and pasted some possibly useful outputs there.

Do you have the latest BIOS?
Do you get sound in headphones?

I hadn't installed the latest BIOS but just did. The problem persists. No sound in headphones.

Here is the new alsa-info output:
http://alsa-project.org/db/?f=f2b70f6eb1a237378bf563cacb6f192ce0a677c3

Here is the output from "Step 4" on the troubleshooting page:

Might be worth noting that the sound card appears on alsamixer but not on pavucontrol. On alsamixer only S/PDIF appears. Images in drive below.

I think I can refine the problem a little bit. ALSA/Pulseaudio is only detecting the HDMI output on my sound card, but not the analog output. I tried running

harrison@lassen:~$ pactl load-module module-detect
Failure: Module initialization failed

When I plug an HDMI output into the laptop, the sound will play from there, which confirms this.

There's something that's confusing me now. The specs for this laptop (which I confirmed using the serial number):
https://topics-cdn.dell.com/pdf/latitude-15-9510-2-in-1-laptop_owners-manual5_en-us.pdf
say the audio controller and speakers are supposed to be
 Realtek ALC711-CG (controller)
 Realtek ALC1309D (speaker)

However, I'm only finding two devices:
 Intel Kabylake HDMI (0806:280b)
 Multimedia audio controller (0806:02c8)

I suppose this could mean either it's using the wrong driver (i.e. cannot properly detect the device) or the above two are some other devices on the motherboard and the audio card is not being detected. Anyway, I feel like I'm narrowing the problem down a bit but still not sure what to do...
