+config SOUND
+ bool "Enable sound support"
+ help
+ Support making sounds through an audio codec. This is normally a
+ beep at a chosen frequency for a selected length of time. However
+ the drivers support playing arbitrary sound samples using a
+ PCM interface.
+
+ Note: At present the sound setup is somewhat tangled up in that the
+ audio codecs are called from the sound-i2s code. This could be
+ converted to driver model.
