[SOLVED] MPD and Alsa Problems

Axioen · 2014-10-19 19:12:00

Hi all. I've been struggling with mpd for a long while now. I have alsa up and running perfectly fine, but it will not play well with mpd. I have been trying to fix this problem for a few weeks reading through tons of posts on this forum and others but to no avail.

Side note: This same thing happened on ubuntu last year but I managed to fix it and I have forgotten how

I used Rasi's mpd setup script and am running mpd as user.

Here is my ~/.mpd/mpd.conf

music_directory                  "/home/axioen/Music"
db_file                          "/home/axioen/.mpd/database"
log_file                         "/home/axioen/.mpd/log"
pid_file                         "/home/axioen/.mpd/pid"
state_file                       "/home/axioen/.mpd/state"
playlist_directory               "/home/axioen/.mpd/playlists"
log_level                        "default"
#password                        "password@read,add,control,admin"
#default_permissions             "read,add,control,admin"
#user                              "axioen"
#bind_to_address                 "10.0.0.1"
bind_to_address                  "127.0.0.1"
bind_to_address                  "/home/axioen/.mpd/socket"
port                             "6600"
gapless_mp3_playback             "yes"
auto_update                      "yes"

audio_output {
               type             "alsa"
               name             "Alsa output"
#               device           "hw:0,0"
#               format           "44100:16:2"
               mixer_type       "software"
#               mixer_device     "default"
#               mixer_control    "PCM"
#               mixer_index      "0"
}

Running

 mpd --no-daemon --stdout -v

returns no errors until I try to play song, it returns

alsa_output: Failed to open "Alsa output" [alsa]: Failed to open ALSA device "default": No such file or directory
output: Failed to open audio output

Commenting out the audio_output section returns

useradd -G audio axioen
useradd: user 'axioen' already exists

I have tried running it as root and other things but it always gives me the same error.

I don't know if it matters, but I also have pulseaudio installed.
Changing the mpd.conf audio output to pulse works but it is highly distorted.

All help appreciated, thank you.

Update: The solve was removing

 replaygain "album"

from the bottom of my ~/.mpd/mpd.conf

First of all, you normally should not add your user to audio group. Second, do it like this: gpasswd -a axioen audio

I don't know if it matters, but I also have pulseaudio installed.

Yes, you should use the pulse output. check the levels of your soundcard with "alsamixer -c 0"
and if necessary lower them. Also watch the sliders in pavucontrol

Thanks for the tips. I enabled the pulse audio output and it's working, yet everything is still distorted. I have all the sliders very low (alsamixer and pavucontrol).

Solved. I'm using only

audio_output {
type "pulse"
name "Pulseaudio
}

The problem was

replaygain "album"

At the bottom of the config file created by the mpdsetup script.

Any ideas on why thats causing a problem?

hmm... sounds like corrupt replaygain tags in your files. I would like to see one of those..
can you join #mpd on freenode and ping me?
