This does not look right:

# groups mpd
mpd : audio

This means that mpd's primary group is not audio.

/etc/mpd.conf

audio_output {
         type            "alsa"
         name            "ALSA sound card"
}

An absence of 'group' stanza means, according to the configuration file:

# This setting specifies the group that MPD will run as. If not
# specified primary group of user specified with "user" setting will be
# used (if set).
# This is useful if MPD needs to be a member of group such as "audio" to
# have permission to use sound card.

My suspicion is that mpd simply discards membership of 'audio' group
then run as a daemon.

So, try this /etc/mpd.conf:

group "audio"

audio_output {
         type            "alsa"
         name            "ALSA sound card"
}
