Hello,

The build seems ok as you have the binary.

Goplay connect to pulseaudio to play the music.
This error occurs when pulseaudio is not installed or if you have a specific setup.

You can also try to install it with apt.

Also, Raspian has introduced pulseaudio as default audio system in version 12.

Then, you could try to upgrade your distribution.

Some reference on pulseaudio on raspian:

Hi, thanks for responding.

I do already have pulseaudio installed, sorry, should have included that info.

pi@raspBplus-api:~ $ sudo apt install pulseaudio

pulseaudio is already the newest version (12.2-4+deb10u1+rpi3).

It's running

Usually the other raison why this happens is because pulseaudio isn’t started for your user (or when running goplay2 as root or with sudo ) but in your report you seems to be running goplay with pi user and pulseaudio seems started.

Are you connected thru ssh or are you trying to run it from a terminal desktop ?

If you can try to run Gooplay2 from a desktop terminal, you should have pulseaudio started.

The error in any case means pulseaudio socket is not found. If you find where he is located on your OS, it might help resolve the issue ( and I can add a parameter to the program).

you can start looking at systemd unit file for pulseaudio (service and/or socket)

Thanks for your message. Yes, this is a raspberry pi headless.

Success!
I was running pulse in daemon mode like pulseaudio -D but instead I needed to run it like pulseaudio --start and add as a systemd service.

Thanks again
