No Audio, PAVU Control Shows Dummy Output

I recently installed Arch and have run into an issue of no audio.  PAVU Control shows "Dummy Output" as the output device. 

speaker-test -c2 plays sound on both laptop speakers
alsamixer has been checke and everything is unmuted

I have provided some output below which I hope is somewhat helpful.  Please let me know if anything else is needed. 

Below is the output of lspci.

Re: No Audio, PAVU Control Shows Dummy Output

Have you got pulseaudio-alsa installed?

Re: No Audio, PAVU Control Shows Dummy Output

That ALSA config will lead to exclusive access for anything that starts to play audio and uses the ALSA API, you should remove it and opt for pulseaudio-alsa instead. What's your output of 

sudo fuser -v /dev/snd/*

during this? And why are you the root user in these outputs? Do you start your graphical session as root? That would also be a big no.

Re: No Audio, PAVU Control Shows Dummy Output

I have added myself to the /etc/sudoers file.  It is a fresh install and I would use su in the terminal to gather the output.

[deep@envy17t ~]$ sudo fuser -v /dev/snd/*
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  deep        748 F.... pulseaudio

Re: No Audio, PAVU Control Shows Dummy Output

OP -- I don't have the solution and do not intend to hijack, but I think this discussion is worth continuing.  I have also struggled with the dummy output issue in the last 1-2 months.  I use DWM and Gnome with same issue across both on various arch 5.10 kernels, LTS 5.4, and mainline kernels. I have spent in inordinate amount of time on archwiki ALSA/Pulseaudio as well as the the documentation for ALSA.  I cannot use alsamixer or amixer without sudo or root access.  Various suggestions like adding user to audio group, etc. have proved unfruitful.

I currently am using TOSLINK/SPDIF out of ASUS mobo but this issue also occurs with normal 1/8 inch out and headphones.   

**To restore sound, the only reliable solution I've found is to delete entire pulse folder in ~/.config/ and completely shutdown.  Reboot into DWM - sound is restored and dummy output is gone --  replaced with AMD Starship/Matisse or whatever is appropriate for your hardware.  This does not work if I shutdown and directly boot into gnome (via startx /usr/bin/gnome-session).

The only commonality I've seen is that this always occurs with intel mobo onboard audio.  Still looking for root cause myself.

Re: No Audio, PAVU Control Shows Dummy Output

I have the exact same issue or at least something related.

A freshly installed Arch install has no audio. I only see Dummy Output in pavucontrol.

The good thing is, I do see the controller with lspci

lspci | grep Audio
00:1f.3 Multimedia audio controller: Intel Corporation Tiger Lake-LP Smart Sound Technology Audio Controller (rev 20)

The alsamixer application only shows PulseAudio as the selected card however.
When I F2 to see the cards there are no cards to be displayed.

I would appreciate some advice!

Re: No Audio, PAVU Control Shows Dummy Output

easylee, you probably need the sof-firmware package, that should be a different issue than codehaiku.

Thank you. I now also found it in the ArchWiki (https://wiki.archlinux.org/index.php/Ad … A_Firmware) and it resolved my problem.

Re: No Audio, PAVU Control Shows Dummy Output

I had a dummy output problem recently also, it seemed to arise with the upgrade of pulseaudio-14.2-2. I found that the conf file for my steelseries headset used to be located in "/usr/share/pulseaudio/alsa-mixer/profile-sets/", but I understand recently this has changed as per Reddit Pulseaudio Post to "/usr/share/alsa-card-profile/mixer/profile-sets/".
Check if the conf file for your sound device is in the new profile-sets directory. HTH.

Re: No Audio, PAVU Control Shows Dummy Output

No it has been changed back to the /usr/share/pulseaudio location due to conflicts with the available profile versions between (pipewire) alsa-card-profiles and what the stable pulse release ships. This also is generally unlikely to be the issue here.

@codehaiku sorry this drowned a bit please post 

systemctl --user status pulseaudio
pacmd list-cards
pacmd list-sinks
