What I tried and worked well is to add the bluetooth device (if it’s a a2dp speaker) to mpd. conf

like this:

audio_output {
        type            "alsa"
        name            "bluealsa"
        device          "bluealsa"
        mixer_type      "software"
}

Pro: this solution it should use lesser CPU than an snd_aloop
Con: it also needs to extend the mpd.conf.tmpl by this section and requires a restart of mpd after changeing the device
