+.B \-channels <number> (also see \-af channels)
+Request the number of playback channels (default: 2).
 MPlayer asks the decoder to decode the audio into as many channels as
 specified.
 Now it's up to the decoder to fulfill the requirement.
-If the decoder outputs more channels than requested, the exceeding channels
-are truncated.
 This is usually only important when playing videos with AC3 audio (like DVDs).
 In that case liba52 does the decoding by default and correctly downmixes the
 audio into the requested number of channels.
+To directly control the number of output channels independently of how many
+channels are decoded, use the channels filter.
