+### Configure Plexamp Headless
+Once started I recommend settings these settings for optimal experience:
+```bash
+# Do not mixdown to stereo (val: true/false)
+echo "Bfalse" > ${HOME}/.local/share/Plexamp/Settings/%40Plexamp%3Asettings%3AaudioMixdownToStereo
+
+# Set cache size to 512MB (val: 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072)
+echo "N512" > ${HOME}/.local/share/Plexamp/Settings/%40Plexamp%3Asettings%3AcacheSize
+
+# Set how many songs to precache on WiFi (val: 0/5/10/15/20/25/40)
+echo "N0" > ${HOME}/.local/share/Plexamp/Settings/%40Plexamp%3Asettings%3AcachingWiFi
+
+# Set player name (Marantz here)
+echo "SMarantz" > ${HOME}/.local/share/Plexamp/Settings/%40Plexamp%3Asettings%3AplayerName
+
+# Set precache network speed to 10Mbps (val: 0/1/5/10/50/100)
+echo "N10" > ${HOME}/.local/share/Plexamp/Settings/%40Plexamp%3Asettings%3AprecacheNetworkSpeed
+
+# Set sample rate conversion quality to highest (64 point sinc) (val: 0-4)
+echo "N4" > ${HOME}/.local/share/Plexamp/Settings/%40Plexamp%3Asettings%3AsampleRateConversionQuality
+
+# Set sample rate matching to "Strict" (val: 0-2)
+echo "N2" > ${HOME}/.local/share/Plexamp/Settings/%40Plexamp%3Asettings%3AsampleRateMatching
+```
+_I don't recommend accessing the Plexamp Headless webUI as it might cause issues with the hack (not tested though)._
+
+#### Setup output device
+I had to manually overwrite the default connection as I wanted to output to a S/PDIF device, check your devices with `aplay -l` :
+```
+**** List of PLAYBACK Hardware Devices ****
+card 1: PCH [HDA Intel PCH], device 0: ALCS1200A Analog [ALCS1200A Analog]
+  Subdevices: 1/1
+  Subdevice #0: subdevice #0
+```
+
+Create the file ``/etc/asound.conf`` and modify it to match your device, this worked for me:
+```
+pcm.!default {
+    type plug
+    slave {
+        pcm "iec958:CARD=PCH,DEV=0"
+    }
+}
+
+ctl.!default {
+    type hw
+    card PCH
+}
 ```
