Something else is using port 6600

Try this:
netstat -tulpn | grep 6600

swh · March 11, 2023, 2:01pm

❯ netstat -tulpn | grep 6600
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

Tried with sudo, nothing shown.

Kill all instances of mpd

mpd --kill
killall mpd

Then try starting mpd via a terminal.

mpd --verbose

swh · March 11, 2023, 2:09pm

❯ mpd --kill

MPD seems to be running.

Could you try connecting to mpd with a frontend?

Or just run mpc update

swh · March 11, 2023, 2:14pm

❯ mpd update
exception: Failed to open 'update': No such file or directory

No, i try with cantata but did not start

flyingcakes · March 11, 2023, 2:15pm

its mpc, not mpd

swh · March 11, 2023, 2:15pm

oh sorry, typo

❯ mpc update
zsh: command not found: mpc

flyingcakes · March 11, 2023, 2:20pm

sudo pacman -S mpc

flyingcakes · March 11, 2023, 2:20pm

Also, which DE/WM are you using?

swh · March 11, 2023, 2:22pm

Im using Plasma running Cantata as client. But Cantata didnt start anymore as i began to start mpd. something is going wrong from this point on

flyingcakes · March 11, 2023, 2:23pm

Install mpc

Run mpc update

And tell if it throws any error

swh · March 11, 2023, 2:25pm

seems there is no error.

❯ mpc update
Updating DB (#1) ...
volume:100%   repeat: off   random: off   single: off   consume: off

trying to start mpd again

flyingcakes · March 11, 2023, 2:26pm

Okay so it works. No issues with config as such.

Lets kill the server and try starting as systemd service.

mpd --kill
killall mpd

And start service as user.

systemctl --user start mpd.service

Then check systemctl status mpd

swh · March 11, 2023, 2:27pm

All done.

Does the default config at /etc/mpd.conf exist?

flyingcakes · March 11, 2023, 2:32pm

Also, you could leave the systemd service altogether and start mpd by itself. (Thats how I prefer it and its never errored out)

Adding mpd to the KDE startup commands / script should do the trick.

swh · March 11, 2023, 2:32pm

No couse i have backed it up as mpd00.conf. i need to rename it?. i was under the impression that mpd creates the file again on startup
