[Solved] MPD: No mixer

SanTDR · 2018-07-13 14:21:15

Hi everyone.

I'm trying to run mpd+ncmpcpp, but I'm getting no sound output from ncmpcpp nor from

mpc play

. My mpd.conf at the moment is:

pid_file "/run/mpd/mpd.pid"
db_file "/var/lib/mpd/mpd.db"
state_file "/var/lib/mpd/mpdstate"
playlist_directory "/var/lib/mpd/playlists"
music_directory "/path/to/music"
bind_to_address "127.0.0.1"  
log_file "/var/lib/mpd/mpd.log"

audio_output {
        type            "pulse"
        name            "pulse audio"
        mixer_type      "hardware"      # optional
        mixer_device    "default"       # optional
        mixer_control   "PCM"           # optional
        mixer_index     "0"             # optional
}

audio_output {
    type                    "fifo"
    name                    "my_fifo"
    path                    "/tmp/mpd.fifo"
    format                  "44100:16:2"
}

With this configuration trying to change the volume, which is displayed as n/a, returns the error MPD: No Mixer, having tried both hardware and software mixer types.

mpd.log:

Alos post both /etc/mpd.conf and ~/config/mpd.conf

That indicates you're using "Per-user configuration" .
To make that work with pulseaudio you need to allow autospawn in /etc/pulse/client.conf .

re-read https://wiki.archlinux.org/index.php/Mu … figuration .

Thank you! I had checked autospawn being on but I had uncommented/commented back the commented autospawn line, not noticing I had previously added another at the bottom. Problem solved, mpd+ncmpcpp works now.
