Sound not working on chromebook. ALSA "unable to open slave"

I recently installed arch on an HP chromebook. I've been trying to set up sound with alsa, but my speakers are still not working. When I run alsamixer, I get this:

instead of what I expected, something like this:

alsamixer

It seems as if none of the channels are muted, so I tried doing a speaker test:

$ speaker-test -c 2

speaker-test 1.2.1

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1089:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory

With this result. To give you more complete information, here's my sound card:

$ cat /proc/asound/cards
0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xc2b18000 irq 127

Has anyone had a similar issue? Is there any more information I should share to get an answer?

Thanks for any and all help.

Re: Sound not working on chromebook. ALSA "unable to open slave"

I don't have your soundcard but for me alsa-lib on Braswell is broken.
Downgrade to alsa-lib 1.1.9-2 fixes it.

$ cat /proc/asound/cards
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xd1314000 irq 315
 1 [chtrt5650      ]: chtrt5650 - chtrt5650
