Hello, I have a problem with the Audacity application. When I play the audio file on the application, it plays without sound. I installed the latest version of the application, and the problem still exists
Ubuntu MATE 18.04 LTS hasn't been supported in a very long time
Even Ubuntu 18.04 LTS ended its standard support by the Ubuntu community, and is now in extended support provided by the company Canonical only
Why ask for support, on a product that is no longer supported here? Generic Unix & Linux support will of course still exist elsewhere.

If sound is otherwise working on the system; then it's likely a setting within Audacity. If you're using snap; then the problem might lie there (some sort of regression in permissions). Some more details about which version you're using and how you are installing it would be useful. I'd be surprised if this was an issue with UbuntuMATE specifically. You could also try the Audacity-specific forum: https://forum.audacityteam.org/

I had that problem for a while too, but figured out Audacious now supporst pipewire along with alsa. You have to go to output> audio settings> audio and change the setting to the correct one. If you are running an older out of date system you may have to put it back on alsa, if you are running updated audacious and your system supports pipewire, you may have to put in on pipewire.

Audacious and Audacity might be different in this regard; but it did cross my mind that there might be a backend issue (i.e. pipewire vs alsa) that could be coming in to play.

Oops, I read that wrong, thank for catching that.
Audacity I would check edit>preferences>audio settings> host and playback device.
I use Pipewire for Audacious, but it doesn't come up on Audacity as a host option on my system, only Alsa. Playback device gives 15 different options on my system, many that don't exist on my system. If not on the correct one you wouldn't have sound.

Audacity only supports ALSA but pulseaudio catches it without problem.
It works for me on 22.04 and 24.04 out of the box, without changing any settings.
I tested on the systems mentioned below:

See if you get any suspected differences, use inxi -xxAC for the same kind of output like above.
