     Audio mixer to use.
 
-    Expects a GStreamer mixer to use, typical values are: ``software``,
-    ``autoaudiomixer``, ``alsamixer``, ``pulsemixer``, ``ossmixer``, and
-    ``oss4mixer``.
-
     The default is ``software``, which does volume control inside Mopidy before
     the audio is sent to the audio output. This mixer does not affect the
     volume of any other audio playback on the system. It is the only mixer that
     will affect the audio volume if you're streaming the audio from Mopidy
     through Shoutcast.
 
-    If you want to use a hardware mixer, try ``autoaudiomixer``. It attempts to
-    select a sane hardware mixer for you automatically. When Mopidy is started,
-    it will log what mixer ``autoaudiomixer`` selected, for example::
-
-        INFO     Audio mixer set to "alsamixer" using track "Master"
-
-    Setting the config value to blank turns off volume control.
+    If you want to use a hardware mixer, you need to install a Mopidy extension
+    which integrates with your sound subsystem. E.g. for ALSA, install
+    `Mopidy-ALSAMixer <https://github.com/mopidy/mopidy-alsamixer>`_.
