Audio not working new install, no soundcards or only HDMI soundcards

I've been trying to fix this for days with no avail. The Sound is not working on my laptop with new arch install.
I'm using a chromebook asus c434 with MrChromebox's uefi installed (so no chromeos, just arch).

I've been through the wiki and tried a lot of things from many forums.
I'm not a very experienced linux user so I will post the output of various commands I have seen on other threads discussing similar issues.
I have alsa, pulseaudio, alsa-firmware, sof-firmware, alsa-ucm-conf, as recommneded by forums and the wiki.

With these packages installed I get

> aplay -l

aplay: device_list:274: no soundcards found...
> pacmd list-cards                                                              
0 card(s) available.

list-sinks only lists one sink, the dummy output

I see people suggested  adding to modprobe

> options snd-intel-dspcfg dsp_driver=1

with this i do get sound cards, but only hdmi which I can't test as I dont have a HDMI port (or a usb-c doc with a port). I don't see any analogue or digital cards like in other people's output.

Any help would be greatly appreciated, sorry if I am missing output from a command I should have tried.

Re: Audio not working new install, no soundcards or only HDMI soundcards

  1. How do you test whether audio is working?

  2. Did I correctly understand that only with

    > options snd-intel-dspcfg dsp_driver=1

    you get

    > aplay -l                                                                      ~

Re: Audio not working new install, no soundcards or only HDMI soundcards

Chromebooks very often use custom firmware that hasn't been upstreamed to any of the standard locations, you need to find firmware specific to your exact chromebook model. And additionally it's likely the UCM config/pin layout is undocumented and hasn't gotten fixed yet, see e.g. : https://www.reddit.com/r/chrultrabook/c … flip_c434/

Re: Audio not working new install, no soundcards or only HDMI soundcards

@regid
Yes, I only get that output when I add 

options snd-intel-dspcfg dsp_driver=1

to modprobe, otherwise I get no devices listed. I tested audio by selecting the cards that appeared with alsamixer, putting up the volume, and running speaker-test.

@V1del
So, I would have to compile or obtain chromeOS for my specific board, and copy over the relevant firmware that deals with audio into the kernel? I found this
audio stuff that matches my specific board: https://chromium.googlesource.com/chrom … vana/audio
I can't say I understand anything about these files, but would this be on the right track?

I find it remarkable the rest of the system works so flawlessly, the camera, buttons, ports, bluetooth, wifi, etc; only the audio doesn't work. Why is it that these do not need me to get custom firmware too?
