+ * Basic mode of operation:
+ *
+ * we have one keyboard (which receives commands from the keyboard)
+ * and multiple headset's connected to audio cards. Headsets are named as
+ * the sections of oss.conf
+ *
+ * At any time, the keyboard is attached to one headset, and you
+ * can switch among them using the 'console' command.
+ *
+ * The following parameters are important for the configuration of
+ * the device:
+ *
+ *  FRAME_SIZE	the size of an audio frame, in samples.
+ *		160 is used almost universally, so you should not change it.
+ *
+ *  FRAGS	the argument for the SETFRAGMENT ioctl.
+ *		Overridden by the 'frags' parameter in oss.conf
+ *
+ *		Bits 0-7 are the base-2 log of the device's block size,
+ *		bits 16-31 are the number of blocks in the driver's queue.
+ *		There are a lot of differences in the way this parameter
+ *		is supported by different drivers, so you may need to
+ *		experiment a bit with the value.
+ *		A good default for linux is 30 blocks of 64 bytes, which
+ *		results in 6 frames of 320 bytes (160 samples).
+ *		FreeBSD works decently with blocks of 256 or 512 bytes,
+ *		leaving the number unspecified.
+ *		Note that this only refers to the device buffer size,
+ *		this module will then try to keep the lenght of audio
+ *		buffered within small constraints.
+ *
+ *  QUEUE_SIZE	The max number of blocks actually allowed in the device
+ *		driver's buffer, irrespective of the available number.
+ *		Overridden by the 'queuesize' parameter in oss.conf
+ *
+ *		Should be >=2, and at most as large as the hw queue above
+ *		(otherwise it will never be full).
