ALSA works, but Pulseaudio and Pipewire do not

Hello, I have a headless system that plays HDMI audio perfectly fine when using ALSA, but I want to switch to Pipewire or Pulseaudio as I understand they are good for having multiple programs playing audio at once (which I occasionally wish to do).

I cannot get either Pulseaudio or Pipewire (with the pipewire-pulse package) to work. I currently have Pipewire installed. Here is the output of a few commands which might be useful:

aplay -l

Can anyone please help? I have been at this for hours and am feeling a bit dumb as I am sure the answer must be simple.

Thanks

Re: ALSA works, but Pulseaudio and Pipewire do not

Welcome to the boards

If the aplay -D plughw:0,x commands do not work, then that would mean ALSA audio output doesn't work. What are you using to test to say that ALSA output works/used to work? Double check that the monitor volume is actually okay and not muted. FWIW with the active mpv playing what's your

pactl list sink-inputs

Re: ALSA works, but Pulseaudio and Pipewire do not

Thanks for the quick response.

When I uninstall pulseaudio or pipewire and reboot (so as to revert backto ALSA), audio works perfectly with the

aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Right.wav

command, as well as in Kodi.

Here is the requested output of the pactl command while pipewire is active, and mpv is playing:

pact list sink-inputs

The display's speakers are definitely not muted. I've tried power cycling everything many times as well.

Re: ALSA works, but Pulseaudio and Pipewire do not

mhm... But with that fuser output your actual device  should not be blocked off for ALSA outputs. How do you start kodi? If you're going from a normal desktop session I wouldn't expect it to be explicitly started as the Kodi user. How do you log in? It could also be an interference by having your user in the audio group, which isn't normally necessary and might lead to clashes with the dynamic access associations systemd/logind usually would want to do.

If you are trying to use different users for kodi/normal session that will likely bite itself, as both of these sound servers are normally set up to be used and controlled via a single user.

Re: ALSA works, but Pulseaudio and Pipewire do not

Kodi is started automatically at boot with the following systemd service:

[Unit]
Description=Kodi standalone (X11)
After=remote-fs.target systemd-user-sessions.service network-online.target nss-lookup.target sound.target bluetooth.target polkit.service upower.service mysqld.service tvheadend.service
Wants=network-online.target polkit.service upower.service
Conflicts=getty@tty7.service

[Service]
User=kodi
Group=kodi
PAMName=login
TTYPath=/dev/tty7
Environment=WINDOWING=x11
ExecStart=/usr/bin/xinit /usr/bin/kodi-standalone -- :0 -quiet -nolisten tcp vt7
ExecStop=/usr/bin/killall --user kodi --exact --wait kodi-x11
Restart=on-abort
StandardInput=tty
StandardOutput=journal

[Install]
Alias=display-manager.service

There is no GUI on this box, so I don't really log in, if I am understanding the question correctly. The Kodi application (and mpv, aplay, etc) is run as the "kodi" user. There is one other "nuc" user that I use for when I need privileged access. I log in via SSH on either account. Am I doing something wrong with this setup? I tried removing the "kodi" user from the "audio" group but unfortunately that did not appear to help. The aplay command still didn't produce any audio.

Re: ALSA works, but Pulseaudio and Pipewire do not

The problem here is that this will lead to two distinct pipewires being started that will fight for the audio device. if you don't start or rather stop the running kodi does the pipewire of your login session still have issues or vice versa? FWIW see https://gitlab.freedesktop.org/pipewire … issues/237 for a discussion of this special usecase. You can workaround by enabling TCP sockets so that one of the pipewires is the "master" and new connections run via the tcp socket: https://gitlab.freedesktop.org/pipewire … otocol-tcp

Re: ALSA works, but Pulseaudio and Pipewire do not

I disabled the pipewire systemd units for the "nuc" user, and disabled the Kodi systemd unit above to prevent it from auto starting, then rebooted the machine. Logged in via SSH as the "kodi" user and ran the aplay command, and there is still no audio. Same results as when I remove pipewire and install pulseaudio instead. I only get audio with ALSA (that is, when pipewire and pulse are not active).

Having multiple users play audio at the same time is not a strict requirement for me, so I am happy to just enable pipewire/pulse service for the "kodi" user. I just can't get either of them to work in the first place, unfortunately.

Re: ALSA works, but Pulseaudio and Pipewire do not

For pipewire:
If you have no audio try to switch the 'Profile' in pavucontrol (most right tab - "Configuration"). I know you're headless but i can't help you any further on that. You have to figure out the cli commands yourself. Maybe try 'pactl'.

Edit: On cli it goes like this:

pactl list cards |grep -E --color=always '^Card|Active Profile:|Profiles:|$'
pactl set-card-profile 46 output:analog-stereo

Follow my grep highlights, find your 'Card #' and profile options and set the new profile.

Which led me to run the following command:

pactl set-card-profile 37 output:hdmi-stereo

And it appeared to set the profile as expected, but unfortunately there was still no audio. Here is the output of 'pactl list cards' after setting the profile, in case there are any further clues in it:

pactl list cards |grep -E --color=always '^Card|Active Profile:|Profiles:|$'

Re: ALSA works, but Pulseaudio and Pipewire do not

1) Can you post a 'pw-dump > pwdump.txt' and 'pacman -Qs pipewire'?

2) Also try these profiles:
pro-audio
output:hdmi-surround71
output:hdmi-surround

You actually were on the 'output:hdmi-stereo' (plus input:) already.

3) Check/handle *.pacnew files in /etc/pipewire

4) Beside that, you should get rid of the the RTKit/nice errors if you add 'threadirqs' kernel parameter. Check if the dbus errors vanish as well. There shouldn't be any errors left in the end.

Re: ALSA works, but Pulseaudio and Pipewire do not

1) The output of pw-dump is here: http://ix.io/3pTT

And the output of the pacman command:

pacman -Qs pipewire

local/pipewire 1:0.3.30-2
    Low-latency audio/video router and processor
local/pipewire-media-session 1:0.3.30-2
    Low-latency audio/video router and processor - Session manager
local/pipewire-pulse 1:0.3.30-2
    Low-latency audio/video router and processor - PulseAudio replacement

2) I had already tried them all, unfortunately still no audio

3) I don't have an /etc/pipewire directory on the system. What does that mean?

4) I added threadirqs to the GRUB_CMDLINE_LINUX_DEFAULT, re-generated the grub.cfg file with grub-mkconfig and rebooted, but the exact same error messages still appear. I also installed the 'rtirq' package

Re: ALSA works, but Pulseaudio and Pipewire do not

You're missing 'pipewire-alsa' package.

No /etc/pipewire folder is ok. It uses the default templates then (/usr/share/pipewire).

4) Maybe you must be in 'realtime' group. You can check the 'professional audio' wiki article.

Re: ALSA works, but Pulseaudio and Pipewire do not

Yeah if you lack pipewire-alsa then aplay commands will naturally not work if the device is actively occupied by a pipewire instance. But the fuser output looked like no device was actively used by anything, other than the seq and control devices which aren't relevant for actual eventual playback.

What happens if instead of running kodi as a system service mapped to a user you instead run it as an actual user service? https://wiki.archlinux.org/title/Systemd/User

I installed the realtime-privileges package and added the "kodi" user to the realtime group as described by the wiki, but the error messages still appear

I created a user service for Kodi and executed it successfully (and with pipewire-alsa installed), but still no audio in kodi/mpv/aplay.

Re: ALSA works, but Pulseaudio and Pipewire do not

so audio output is technically there, what's the output of

sudo fuser -v /dev/snd/*
aplay -lL

during that? I wonder whether the hdmi:0 it picks here is just an invalid PCM due to weird HW setup. Any messages in the journal/dmesg as to why it fails? Does the working ALSA case pick a specific sample rate that might be non-standard?

I don't see any errors related to audio in the journal or dmesg, but on the other hand I'm not quite sure what to look for either.

Is there a command I can run, or some other way to determine whether this is the case?

Regarding the error from your upper post its the 'nuc' user lacking the privileges.

What about plug:pipewire?

aplay -D plug:pipewire /usr/share/sounds/alsa/Front_Center.wav

Try enforcing S16LE or different sample rate:
https://gitlab.freedesktop.org/pipewire … properties

cp -r /usr/share/pipewire ~/.config/pipewire
sed -i 's/#audio.format/audio.format/' ~/.config/pipewire/media-session.d/alsa-monitor.conf
systemctl --user restart pipewire.service pipewire-pulse.service pipewire-media-session.service

Re: ALSA works, but Pulseaudio and Pipewire do not

Found a little more time to tinker with it. While my goal is to switch to pipewire, I uninstalled it and re-installed pulseaudio and pulseaudio-alsa for testing purposes (there are more google search results for people having problems with it, so more things to try).

I noticed that if I uncomment the following line in /etc/pulse/default.pa

#load-module module-alsa-sink

and change it to this:

load-module module-alsa-sink device=hw:0,3

And then reboot, I can successfully play and hear an audio file with MPV and pulseaudio.

The problem is, if I then run Kodi, it still has no audio. And if I then close Kodi and try to play the same audio file with MPV, I hear nothing.

So I try to restart the pulseaudio service:

systemctl --user restart pulseaudio

and run MPV again, but I get an error message and it reverts to ALSA (but I still don't hear anything):

mpv audio_file.flac

 (+) Audio --aid=1 (flac 2ch 44100Hz)
[ao/pulse] The stream is suspended. Bailing out.
AO: [alsa] 44100Hz stereo 2ch s16

If I close MPV and run the same command again, the error disappears and it apparently uses pulseaudio again (but I still don't hear anything):

mpv audio_file.flac

 (+) Audio --aid=1 (flac 2ch 44100Hz)
AO: [pulse] 44100Hz stereo 2ch s16

If I reboot, audio works again, but really only for the first program I run (whether it be Kodi or MPV). I also noticed that if I happen to log in via SSH as a second user, audio will stop working for the first user until the next reboot (same for the second user). EDIT: I'm no longer sure about that last part, I was able to SSH in as two separate users and have one of them play audio successfully.

Here is some system status output as the "kodi" user:

Re: ALSA works, but Pulseaudio and Pipewire do not

All of that is "normal". You can only have one process access the audio device at a time. Which is why pulseaudio and pipewire exist. You need to make sure that kodi runs in a context where it either takes over device completely or connects to the correct pulseaudio/pipewire instance, and it reads like that last part is what you are having trouble with. from this mpv startup attempts what's your output for

printenv 
sudo fuser -v /dev/snd/*

The fuser command is for checking what is actively using the device, you ideally should see only see pulseaudio here and have all relevant audio working, recheck this during the "not working" cases.

Here is the output of printenv (the "kodi" user has very similar output):

The output of fuser (executed by the "nuc" user, while the "kodi" user is successfully playing an audio file with MPV):

sudo fuser -v /dev/snd/*

                     USER        PID ACCESS COMMAND
/dev/snd/pcmC0D3p:   kodi        666 F...m pulseaudio

A few seconds after quitting MPV, the output looked like this:

                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  kodi        666 F.... pulseaudio
/dev/snd/pcmC0D0c:   kodi        666 F...m pulseaudio
/dev/snd/pcmC0D3p:   kodi        666 F...m pulseaudio

Then changed to this:

                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  kodi        666 F.... pulseaudio

And after starting playback with MPV again (can't hear audio anymore though):

                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  kodi        666 F.... pulseaudio
/dev/snd/pcmC0D3p:   kodi        666 F...m pulseaudio

Re: ALSA works, but Pulseaudio and Pipewire do not

Found a little more time to tinker with things this week, and I think I have pulseaudio working reliably (so far, it's only been a few days).

I added these lines to /etc/pulse/default.pa:

load-module module-alsa-sink device=hw:0,3
load-module module-alsa-source device=hw:0,3

And also commented this section out completely, although I have not confirmed if I really needed to:

### Automatically load driver modules depending on the hardware available
.ifexists module-udev-detect.so
load-module module-udev-detect
.else
### Use the static hardware detection module (for systems that lack udev support)
load-module module-detect
.endif

Now I have audio on boot, after switching applications, etc.

I would suppose my question now is, is there an equivalent for the above options if I were to use pipewire? This article could be relevant, but if it is, I might need things to be spelled out a little more.
