+audio_output {
+    type                    "fifo"
+    name                    "glava_fifo"
+    path                    "/tmp/mpd.fifo"
+    format                  "22050:16:2"
+}
+```
+
+Note the `22050` sample rate -- this is the reccommended setting for GLava. Restart MPD (if nessecary) and start GLava with `glava --audio=fifo`.
