No sound and no mic on Dell Latitude 9520

I installed Arch Linux on a Dell Latitude 9520 and can't get the audio/mic to work. The issue looks really similar to the one here: https://bbs.archlinux.org/viewtopic.php?id=260139 but the solution proposed does not work for me.

Here is the output of some relevant commands:

aplay -l

aplay: device_list:274: no soundcards found...

lspci -v | grep "audio"

Re: No sound and no mic on Dell Latitude 9520

Which of the suggestions in the linked thread did you end up trying and what configuration is actually active right now?

Re: No sound and no mic on Dell Latitude 9520

I added to /etc/modprobe.d/alsa.conf:

options snd-intel-dspcfg dsp_driver=1

but this did not work so I resorted to the original configuration.

Re: No sound and no mic on Dell Latitude 9520

Try dsp_driver=2 oh and which kernel? If this is LTS try the normal one.

Re: No sound and no mic on Dell Latitude 9520

Thank you V1del for your prompt responses.

I was on LTS but I have just now tried the normal one. Neither one of the 4 combinations with dsp_driver works sad

Re: No sound and no mic on Dell Latitude 9520

I researched and found that my audio chip is Realtek ALC714-CG. I find very few information by googling it, but apparently its fellow ALC711-CG is not yet well supported:

Re: No sound and no mic on Dell Latitude 9520

Just a long shot, but try installing sof-firmware:

sudo pacman -S sof-firmware

Thank you ! That package is already installed and up to date though.

Re: No sound and no mic on Dell Latitude 9520

It's probably a similar bug like in https://bbs.archlinux.org/viewtopic.php … 6#p1997106 though since it's a different model I don't know whether the quirk mentioned in that bug report would work as well, it appears to check the BIOS version though so if these are shared it will be picked up on the 5.15 kernel.

Re: No sound and no mic on Dell Latitude 9520

Thank you V1del.

Yes, the XPS 17 (9710) ships with Realtek ALC711-CG and I have Realtek ALC714-CG. I would suppose they are very similar?

Re: No sound and no mic on Dell Latitude 9520

The loading failure error message is the same at least, maybe check the posted logs in the bug report I linked and compare e.g. dmidecode whether you turn up the same values. Will probably also not hurt to chime in on that bug report with your own system information (though not sure whether they'd rather want a separate bug or whether it's acceptable to mention you get the same issue on your particular model).
