This seems to be a very common problem. I have tried everything mentioned in the threads online, but nothing has worked.

I have an HP Chromebook 13 G1, and am running Ubuntu 20.04 and my output for uname -srm is Linux 5.13.0-39-generic x86_64.

I installed Ubuntu on the Chromebook by using MrChromebox, I'm not sure if that make a difference to anything. I know for sure the sound worked originally when ChromeOS was installed.

Here are some audio related outputs:

$ lspci -nnk | grep -A2 Audio

00:1f.3 Multimedia audio controller [0401]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d70] (rev 21)
    DeviceName: Multimedia audio controller
    Kernel driver in use: snd_soc_skl

$ aplay -l
aplay: device_list:276: no soundcards found...

$ pacmd list cars |egrep -i "output|active"

    argument: <sink_name=auto_null sink_properties='device.description="Dummy Output"'>
        device.description = "Dummy Output"
        device.description = "Monitor of Dummy Output"
0 source output(s) available.

$ lspci -v | grep -i audio
00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-LP HD Audio (rev 21)
    DeviceName: Multimedia audio controller

I have followed the steps people suggest, but I'm not sure I'm following it correctly. For example, when people suggest to add options snd-hda-intel dmic_detect=0 to /etc/modprobe.d/alsa-base.conf, I am meant to replace snd-hda-intel with snd_soc_skl right?

If anyone can give me some guidance on this, that would be wonderful.

EDIT:

The outputs I listed above were for a clean install of Ubuntu. After I change /etc/modprobe.d/alsa-base.conf to add the lines

options snd-hda-intel model=auto
options snd-hda-intel dmic_detect=0

and I also added blacklist snd_soc_skl to /etc/modprobe.d/blacklist.conf

Now my outputs are like this:

$ lspci -nnk | grep -A2 Audio

00:1f.3 Multimedia audio controller [0401]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d70] (rev 21)
    DeviceName: Multimedia audio controller
    Kernel driver in use: snd_hda_intel

$ aplay -l

Apparently this is a known issue that modern Chromebooks (as of around 2015) do not maintain sound functionality when other versions of linux are installed.

The only exception I know of is GalliumOS. Which version of GalliumOS you need to install depends on the model of your Chromebook, but I found that Skylake allows the sound to work with the HP Chromebook 13 G1.

It's worth noting that bluetooth audio will work with other linux distros, so depending on your situation, it might be suitable to use Ubuntu with a bluetooth speaker, or headphones.
