Cannot record desktop audio (module-echo-cancel)

Summary

I’d like to restore the ability to record desktop audio on my pc.

  • Desktop audio recording does NOT work
  • GNOME Settings does NOT show anything on the volume gauge
  • GNOME Settings displays mic activity on its gauge
  • Audio playback works
  • Mic recording works
  • Weird behaviour of echo-cancelled versions (see #background below)

Attempted solutions

Disabled (?) PipeWire by running systemctl --user disable --now pipewire.socket pipewire.service && systemctl --user mask pipewire.socket as suggested in a previous post.

Background

Before and after every system upgrade, I create a backup of my system using Timeshift. The latest backup was made two days before my latest successful screen recording, which leads me to believe that the updates have not caused the issue at hand, since two reboots lie in between.

I’m also (attempting to ?) use the module-echo-cancel with PulseAudio. This resulted in a manual configuration change in /etc/pulse/default.pa (seee below). Ever since, my mic had better voice cancellation, and two new (virtual) audio devices appeared: Echo-cancelled versions of my speaker and my mic.

From then on, I always used the original entry for my speaker and the new echo-cancelled one for my mic. This was more than ten months ago, there were no issues until now.

For the config file, please note only the last block has been changed (added by me), the rest is the default which came with Manjaro:

.endif

A surprising discovery

Turns out that the echo-cancelled version of my speakers (when selected) shows up in the audio gauge of GNOME Settings, is picked up by OBS but only supports mono audio??

When clicking on test, rather than hearing Front Right and Front Left, I only see one button (opposed to the two which usually show up) labeled “Mono”. Clicking on it only produces static - but media playback works (apart from being mono-only).

Diagnostics

My PC is running Linux 5.15.12-1-MANJARO. I ran the two suggested commands to get info useful for troubleshooting inxi -Aa & sudo alsa-info.sh and pasted their respective outputs below.

TL;DR

  • I cannot record my desktop audio
  • Only the (mono-only) echo-cancelled version of my speakers can be recorded
  • Mic recording & audio playback works fine

Thank you so much for reading and your for your time!

Given this information, how should I proceed?
Would undoing the changes made to /etc/pulse/default.pa be a good idea and can I still use echo-cancellation?

You can either use pulseaudio or pipewire. Having both installed will lead to errors.
You should uninstall the one you don’t want.

Thanks for your reply!

sudo pacman -R pipewire yeilds the following dependency errors:

Should I force-remove?

Remove manjaro-pipewire or install manjaro-pulseaudio.

It will take care of the dependencies. (Be careful to check what will be removed, as you already did before)

Running sudo pacman -Sy manjaro-pulse --needed yields

 core is up to date

warning: manjaro-pulse-20211001-1 is up to date -- skipping

and sudo pacman -R manjaro-pipewire results in

error: target not found: manjaro-pipewire

Notice: I wrote manjaro-pulse instead of manjaro-pulseaudio, because that doesn’t exist either :thinking:

I use gnome-sound-recorder.

How does that work on KDE then? KDE has both installed by default, this is not an issue. You can’t even uninstall Pipewire as it is a dependency of KDE itself (I know here the user has GNOME, but that’s not the point).

Thanks for the suggestion, but I believe recording desktop audio is not supported.

Can gnome-sound-recorder record desktop audio?
I know it can record my mic, but I want to record my desktop audio (preferably using OBS, like I have done for months before it broke)

This is probably an issue with how I configured the echo-cancellation module, right?

I don’t know about the echo-cancellation module, but recently to record my computer audio I used this method Tutorial - Recording Computer Playback on Linux - Audacity Manual

Basically using pavucontrol to set in the Recording tab the “Monitor of XXX” instead of “XXX” (try to follow the tutorial).

The core pipewire package is required by OBS and Telegram so cannot be removed
But PipeWire systemd socket & service can be disabled/masked to continue using PulseAudio, as already mentioned in OP
(replacement package pipewire-dummy from AUR works with OBS but not with Telegram)

I suggest adding additional options to module-echo-cancel configuration to force use of 2 stereo channels, either channels=2 and/or use_master_format=1

If audio is still not working as expected, check PulseAudio configuration with pacmd dump

Setting use_master_format=1 has lead to the echo-cancelled output being stereo.

This are the current trailing lines of my config:

.ifexists module-echo-cancel.so
load-module module-echo-cancel aec_method=webrtc source_name=echocancel sink_name=echocancel1 use_master_format=1
set-default-source echocancel
set-default-sink echocancel1
.endif

I’m now using this echo-cancelled version of my speakers in my GNOME Settings panel, and they also work in OBS.

Thanks for the suggestion to add use_master_format=1, that was helpful :+1:

Is there any way to also fix my “normal” speaker in PA?
Removing the echo module didn’t fix it either, currently I’m using the echo-cancelled version of my speaker as a workaround.

Again thanks for your reply! :grinning_face_with_smiling_eyes:

What could be the issue resulting in my normal desktop audio not being recordable?

Yes, the workaround proposed here works, but I’d like to solve/understand the underlying problem.

Thanks for your patience

PS: Why did the workaround get accepted as the solution (I didn’t do that)? And now the thread is marked to be closed after three days of inactivity.

I would consider use of additional options to load extra modules to be usual procedure for users setting up PulseAudio. If a module does not work as expected in basic form there are many documented options to change the audio stream

I suggest you check configuration of PulseAudio audio sources

pacmd dump && pacmd list-sources

and check audio capture stream to OBS

pacmd list-source-inputs

Below is the command output of pacmd dump && pacmd list-sources, the other command only got me Unknown command: list-source-inputs.

I don’t think a config issue in OBS is causing this, as only the echo-cancelled sink of my speakers can have their current volume “measured”. Even GNOME Settings does not show a moving bar in the volume gauge when I play audio using my “normal” speakers in the settings (or in OBS for that matter, when the “normal” one is selected in GNOME Settings).

Both OBS and GNOME settings only show a moving volume-bar when I’m using the echo-cancelled sink, but I can hear audio using both.

Thanks again :+1:

Final command should have been pacmd list-source-outputs, but is not needed. Data from the other command shows the problem in PulseAudio

The Audio output monitor is shown as mured

set-source-mute alsa_output.pci-0000_0b_00.4.analog-stereo.monitor yes

Other sources are shown as unmuted

Use this command to unmute the output monitor

pacmd set-source-mute alsa_output.pci-0000_0b_00.4.analog-stereo.monitor no

or look in GUI audio controls for a mute button

Thank you; this worked!  :tada:   :rocket:

But what does it mean? I always assumed “monitor” to bean playback of a source. So this command un-mutes the monitor aspect (?) of some device/source/? or something like that?

If it’s not too much trouble, where could I learn more about this?

The data from pacmd dump was enough to show the source was muted
(and shows it in a format that can be edited to a command to unmute it)

The data from pacmd list-sources shows similar data in a different format

	name: <alsa_output.pci-0000_0b_00.4.analog-stereo.monitor>

	muted: yes

PulseAudio has sinks for audio playback to speakers/headphones
not including the echo-cancellation, your system has 2 sinks:
alsa_output.pci-0000_0b_00.4.analog-stereo
alsa_output.pci-0000_09_00.1.hdmi-stereo

For both of the outputs PulseAudio creates a monitor to use as a source for audio capture
alsa_output.pci-0000_0b_00.4.analog-stereo.monitor (audio playing to headphone/speakers)
alsa_output.pci-0000_09_00.1.hdmi-stereo.monitor (audio playing to monitor speakers)

The HDMI does not have audio inputs, so the only hardware source is:
alsa_input.pci-0000_0b_00.4.analog-stereo (microphones)
