Enable volume buttons

[opi]

(Hi, thanks for this awesome piece of software !)

I wonder how enable the volume buttons ? I guess it is MPD related, maybe something with the mixer configuration, but my knowledge is somehow limited.

thanks

Hi there,

You are correct! That happens because your MPD can't control the volume for some reason. You'll probably have to open /etc/mpd.conf and edit the audio_output section, specially the mixer related options.

The exact configuration varies according to your system, so I suggest you to look at the MPD documentation here and here.

Just to make sure you didn't bump into a bug in PiFi and it's really on the MPD side, can you please do the following?

1. Install mpc with sudo apt install mpc
2. Run the following commands and paste the output here:

mpc volume
mpc volume 100
mpc volume -10

Btw, thanks for the compliment!

I'll look at the MPD documentation about audio output soon. In the meantime, here the output for the mpc commands :

pi@fipbox:~ $ mpc volume
volume: n/a
pi@fipbox:~ $ 
pi@fipbox:~ $ mpc volume 100
fipreggae-midfi.mp3
[playing] #1/1  48:54/0:00 (0%)
volume: n/a   repeat: off   random: off   single: off   consume: off
pi@fipbox:~ $ 
pi@fipbox:~ $ mpc volume -10
fipreggae-midfi.mp3
[playing] #1/1  48:57/0:00 (0%)
volume: n/a   repeat: off   random: off   single: off   consume: off

and my MPD config is simply :

audio_output {
        type            "alsa"
        name            "My ALSA Device"
        device          "hw:0,0"
}

I'll try various mixer_type, mixer_device and mixer_control ;

Thanks for pasting the output. This confirms the problem is in the MPD end, probably the configuration.

In case this helps you, I use a USB dongle for audio output, and my config is the following:

audio_output {
	type "alsa"
	name "USB audio"
	device "hw:2"
	mixer_type "hardware"
	mixer_device "hw:2"
	mixer_control "Speaker"
}

I'm closing the issue as it is not related to PiFi.

Best regards!

for what it's worth, after playing around a bit i found the following setting to be working for my setup, which is an old raspberry pi with headphones audio output:

audio_output {
        type            "alsa"
        name            "My ALSA Device"
        device          "hw:0"          # optional
        mixer_type      "software"      # optional
        mixer_device    "default"       # optional
        mixer_control   "PCM"           # optional
#       mixer_index     "0"             # optional
}
