Troubles getting snapcast server and client to work.

[ignacio82]

I'm trying to get these to work on my ubuntu server following your tutorials.

Snapcast server cannot start as a service:

$ systemctl status snapserver
× snapserver.service - Snapcast server
     Loaded: loaded (/etc/systemd/system/snapserver.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Tue 2024-01-23 00:40:44 UTC; 14min ago
       Docs: man:snapserver(1)
   Main PID: 2350323 (code=exited, status=217/USER)
        CPU: 851us

Jan 23 00:40:44 mini-server systemd[1]: Stopped Snapcast server.
Jan 23 00:40:44 mini-server systemd[1]: snapserver.service: Start request repeated too quickly.

Jan 23 00:40:44 mini-server systemd[1]: Failed to start Snapcast server.

However, if I run it from the command line it works:

~$ sudo snapserver

Any ideas what might be causing this?

Similarly, snapcast client is not working:

$ journalctl -u snapclient.service -f
Jan 23 00:52:12 mini-server systemd[1]: Started Snapcast client.
Jan 23 00:52:12 mini-server snapclient[2362437]: Exception: PulseAudio context failed, error: Access denied

Jan 23 00:52:13 mini-server systemd[1]: Failed to start Snapcast client.

But i can run it from the command line:

$ snapclient -h 192.168.86.124 --player pulse:property=media.role=music --sampleformat 44100:16:*

Ideas?

I was able to get this to work once by making sure all services were running under my user.

/etc/snapserver.conf

# the user to run as when daemonized
user = ignacio
# the group to run as when daemonized
group = ignacio
