-But playing a mono wav file ... no sound. Not good.
+But playing a mono wav file ... no sound. Not good. Oh, wait, must turn on headphone mixer:
+<code>
+# amixer set "Headphone Mixer" on,on
+Simple mixer control 'Headphone Mixer',0
+  Capabilities: pswitch
+  Playback channels: Front Left - Front Right
+  Mono:
+  Front Left: Playback [on]
+  Front Right: Playback [on]
+</code>
+In short:
+  * switch ''HPOUTL PGA'' to "Mixer"
+  * enable ''HPMIXL DACL''
+  * enable "Headphone Mixer"
+==== Playing mono .wav files on both headphone channels ====
+Seems simple enough:
+  * Switch ''HPOUTR PGA'' to "Mixer"
+  * Make sure "Headphone Mixer" is enabled
+  * Enable ''HPMIXR DACL''
