[SOLVED] Music player daemon: pulse audio output not working.

torronto · 12-11-2020, 12:07 PM

Good afternoon,
After installing mpd and getting some basic configuration done the daemon seems to be running normally but a control client, specifically mpc still states { Volume: n/a}.

mpd.conf:

Code:

# Recommended location for database
db_file            "~/.mpd/database"

# Logs to systemd journal
log_file           "~/.mpd/log"

# The music directory is by default the XDG directory, uncomment to amend and choose a different directory
music_directory    "~/Music"

# Uncomment to refresh the database whenever files in the music_directory are changed
auto_update "yes"

# Uncomment to enable the functionalities
playlist_directory "~/.mpd/playlists"
pid_file           "~/.mpd/pid"
state_file         "~/.mpd/state"
sticker_file       "~/.mpd/sticker.sql"

audio_output {
        type            "pulse"
        name            "pulse audio"
}

MPC Output commands from here:

Quote:

Output Commands

volume [+-]<num> - Sets the volume to <num> (0-100). If
+ or - is used, then it adjusts the volume relative to the current volume.

outputs - Lists all available outputs

disable [only] <output # or name> [...] - Disables the
output(s); a list of one or more names or numbers is required. If “only” is the first argument, all other outputs are enabled.
enable [only] <output # or name> [...] - Enables the
output(s); a list of one or more names or numbers is required. If “only” is the first argument, all other outputs are disabled.
toggleoutput <output # or name> [...] - Changes the
status for the given output(s); a list of one or more names or numbers is

Did you set the volume?

Full commands, full output please. No paraphrasing. And use CODE tags for commands & their output.

Might sound like a stupid question but what's the proper syntax format to adjust the volume?

Code:

mpc volume + 5  
usage: mpc volume [+-]<num>

I don't use mpd, but the following looks wrong:

Code:

name            "pulse audio"

I think pulseaudio should be one word. That might not fix it, dunno, but I would try it.

I'm pretty sure the "Type" variable is the only one that matters. The name part is pretty much just a comment and should be only used for reference.
Anyway, this thread was solved by adding my user to the audio group.

Thanks for sharing the solution.
Maybe some documentation of how you did that?
Others will benefit.

Sure.
For me it was as simple a changing the 'User=' line down in the mpd service file to my own user and adding my user to the audio group.

Code:

/usr/lib/systemd/system/mpd.service

[Service]
User=usr
#Type=notify
PAMName=system-local-login
ExecStart=/usr/bin/mpd --no-daemon


sudo usermod -a -G audio usr
sudo reboot
