No sound on iMac

No, it didn't solve it. (But yeah I think the gedit command still worked, even though it had an error. I mean just that I could edit the file, but sound still doesn't work.)

try this, please:

# Add ppa for latest build
sudo add-apt-repository ppa:pipewire-debian/pipewire-upstream

# Update
sudo apt update

# Install components
sudo apt install gstreamer1.0-pipewire pipewire-media-session libspa-0.2-bluetooth libspa-0.2-jack pipewire pipewire-audio-client-libraries

# If you get unmet dependencies, you can run:
sudo apt --fix-broken install
# Then re-run
sudo apt install gstreamer1.0-pipewire pipewire-media-session libspa-0.2-bluetooth libspa-0.2-jack pipewire pipewire-audio-client-libraries

# Reload new services
systemctl --user daemon-reload

# Disable PulseAudio service
systemctl --user --now disable pulseaudio.service pulseaudio.socket

# If you update from previous version of PopOS
systemctl --user mask pulseaudio

# Enable Pipewire services
systemctl --user --now enable pipewire pipewire-pulse

# Enable Pipewire media session
systemctl --user --now enable pipewire-media-session.service

# Reboot and possibly use https://extensions.gnome.org/extension/906/sound-output-device-chooser/

if you're on gnome, post a screenshot of the extension on this link (Sound Input & Output Device Chooser - GNOME Shell Extensions)

Ok I tried installing it, I don't see anywhere an app though. Or do I need to start it from the terminal? If so how do I do that?

I also tried to get the extension, here I just got a zip file, which unzipped just have several files. How do I install them or use them?

25

You can move / copy the files to either
~/. local/share/gnome-shell/extensions
or to make it system-wide:
/usr/share/gnome-shell/extensions

26

It isn't an app, but a service. It starts when the system boots up

27

But without the extension, does the audio work??

28

Hmm, so still having no sound, but Pipewire services was now installed.
Not sure if the extension got installed or not.

I have the same mac,

Go to settings, Sound, select profile "ANALOG STEREO 4.0"

It shall work
