[Solved] MPD - Ncmpcpp - No audio after enabling the FFT generation

Hello,
I'm a new(and awesomed) Mpd user, I discovered the Ncmpcpp, and following the wiki I tried to enable the visualizations,
But if I add the config lines to  /etc/mpd.conf:

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

And restarts mpd.service the audio stops working, now commenting out that audio_output and restarting again I get the audio.

How can I find the root cause of the problem?

Try setting log_file in mpd.conf and see what it writes to the log.

Did it but nothing relevant in the logs, also it's like it's working fine cause the logs shows the next played song.

Do you have another audio_output in mpd.conf? If not, it will only use the one you have configured.

Does ncmpcpp list all defined outputs? Does the fifo exists/gets created? Ncmpcpp has its own error.log.
Edit: missed the previous post.

could be that the audio output is disabled, double check in ncmpcpp to be sure

Re: [Solved] MPD - Ncmpcpp - No audio after enabling the FFT generation

yes, looks like the problem is that I don't have another audio_output defined, this is the status of the mpd service when I start it without the fifo output:

Jun 04 20:26:18 netarch mpd[560]: output: No 'audio_output' defined in config file
Jun 04 20:26:18 netarch mpd[560]: output: Attempt to detect audio output device
Jun 04 20:26:18 netarch mpd[560]: output: Attempting to detect a alsa audio device
Jun 04 20:26:18 netarch mpd[560]: output: Successfully detected a alsa audio device

So I added the following lines to the mpd.conf:

audio_output {
        type                    "alsa"
        name                    "Sound Card"
        options                 "dev=dmixer"
}

audio_output {
    type                    "fifo"
    name                    "my_fifo"
    path                    "/tmp/mpd.fifo"
    format                  "44100:16:1"
}

Thanks for your help!
