		Enable support for audio device drivers.  This includes drivers for
		MP3, WMA and Ogg Vorbis encoding, decoding, as well as drivers for
		interfacing with external DSP chips to perform custom audio functions.

		NOTE: All of these drivers depend on support from the audio subsystem
		enabled with the AUDIO selection.

		data to the VS1053 driver.  The minimum you should set this is
		2 buffers, which should be adequate for most media types.

	---help---
		Sets the size of the Audio Pipeline Buffers used to deliver audio
