+          Create a new audio device called "Framework Speakers",
+          which applies sound tuning before sending the audio out to the speakers.
+          This option requires PipeWire and WirePlumber.
+
+          The filter chain includes the following:
+            - Pyschoacoustic bass enhancement
+            - Loudness compensation
+            - Equalizer
+            - Slight compression
+
+          This option has been optimised for the Framework Laptop 13 AMD 7040 series, but should work on all models.
+
+          Before applying, ensure the speakers are set to 100%,
+          because the volumes compound and the raw speaker device will be hidden by default.
+
+          You might also need to re-select the default output device.
+
+          In some cases, the added bass will vibrate the keyboard cable leading to a rattling sound,
+          a piece of foam can be used to mitigate this.
