No sound, pulseaudio show dummy output

Hello everyone,

I've installed Arch (5.6.15-arch1-1) on my Acer Chromebook 14 CB3-431 (Edgar).

I have no sound over speaker and headphone jack. Pulseaudio is only showing "Dummy Output". Sound over HDMI is working.
I googled for a while now and tried different solutions, none helped.

Here is some data:

Pulseaudio only detects HDMI sound card.

pacmd list-cards

1 card(s) available.
    index: 0
	name: <alsa_card.pci-0000_00_1b.0>

But Kernel detects second sound card.

cat /proc/asound/cards

Running 

dmesg

I get this same error message a lot:

Running 

pulseaudio -vv

I get following output.

...

So card is detected by the kernel, but Pulseaudio can't load the card.


Hopefully someone can help me.
Let me know if you need any more information.

Re: No sound, pulseaudio show dummy output

I get a similar symptom, Dummy output in pulseaudio/pavucontrol.  I've tracked it down to no analog device detected.  If I run aplay -l, I get the following output:

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 9: HDMI 3 [HDMI 3]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 10: HDMI 4 [HDMI 4]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I've tried removing the PCI device from /sys/buc/pci/devices, unloading all the sound related kernel modules, and then reloading the modules and rescanning the PCI bus (see this post).  Sometimes that works, but tonight I've been unable to resurrect the analog device.

I don't have anything to plug the HDMI output to, so I haven't tested the HDMI output.  I assume there's a conflict between the analog device (which should be "device 0"), and the HDMI subsystem.  I saw on another thread with my exact sound card, to try passing intel_iommu=off to my kernel cmdline, but that didn't seem to change the behavior.

Re: No sound, pulseaudio show dummy output

Thanks for your reply.

Unfortunately this is not working for me.

aplay -l shows shows two cards for me:

 aplay -l

Re: No sound, pulseaudio show dummy output

These kinds of cards are always a pain. FWIW there is betterment in sight for the next round of alsa-lib/pulseaudio releases,  in the meantime something ugly you can try is 

ln -s /usr/share/alsa/ucm2 /usr/share/alsa/ucm

and ensure alsa-ucm-conf is installed. That way you link the old ucm configuration location to the newer API, which while technically incompatible might lead to the card being able to be initialized properly.

Re: No sound, pulseaudio show dummy output

Unfortunally this didn't solve the problem. I installed alsa-ucm-conf and ran above command. Did I miss something?

Meanwhile, running just pulseaudio (whithou -vv) gives a more detailed error description.

Re: No sound, pulseaudio show dummy output

It did in fact change things, it does now try to parse the ucm configuration but fails to do so (which was somewhat expected as the two UCM configuration versions should be incompatible, but there have been devices where this works).

You could also give pulseaudio-git a shot, as it should properly pick up on ucm2 configuration files that way.

Re: No sound, pulseaudio show dummy output

Sorry for the late response I was on vacation.

I installed pulseaudio-git. When running pulseaudio I get the same output as above.
