+		Advanced Linux Sound Architecture - Driver
+		==========================================
+			    Configuration guide
+
+
+Kernel Configuration
+====================
+
+To enable the ALSA support, at least you need to build the kernel with
+the primary sound card support (CONFIG_SOUND).  Since ALSA can emulate
+the OSS, you don't have to choose any of the OSS/Free modules.  Please
+enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and
+PCM supports if you want to run the OSS application with the ALSA.
+
+When you want to support the WaveTable functionality on some cards
+such like SB Live!, you need to enable "Sequencer support"
+(CONFIG_SND_SEQUENCER).
+
+For getting more verbose debug messages, turn on "Verbose printk" and
+"Debug" options.  For checking the memory leaks, you can turn on
+"Debug memory" option, too.  "Debug detection" will put more
+additional checks for the detection of cards.
+
+Please note that all the ALSA ISA drivers support Linux isapnp API (if
+the card supports).  You don't need to configure the PnP via
+isapnptools.
+
+
+Module parameters
+=================
+
+  A user can modify or set parameters at the load time of the module. If
+  the module supports more cards and you have got more than one card
+  of the same type, you may simply specify more values for the parameter,
+  delimited by commas.
+  
+  Note that module option names were changed in 0.9.0rc4. The 'snd_'
+  prefix was removed.
+
+  Module snd
+  ----------
+
+    The module snd is the ALSA core module, which is used by all ALSA
+    card drivers.  This takes the global options for creating devices,
+    etc.
+
+    major	- major # for sound driver
+		- default is 116
+    cards_limit
+		- specifies card limit # (1-8)
+		- good for kmod support if you do not want to search
+		  for soundcards which are not installed in your system
+    device_mode
+		- specifies permission mask for dynamic sound device filesystem
+		- default value = 0666
+		- for example 'device_mode=0660'
+    device_gid
+		- specifies GID number for dynamic sound device filesystem
+		- default value = 0 (root)
+    device_uid
+		- specifies UID number for dynamic sound device filesystem
+		- default value = 0 (root)
+
+  
+  Module snd-pcm-oss
+  ------------------
+
+    The PCM OSS emulation module.
+    This module takes the options to change the mapping of devices.
+
+    dsp_map	- PCM device number maps assigned to the 1st OSS device.
+		  (default: 0)
+    adsp_map	- PCM device number maps assigned to the 2st OSS device.
+		  (default: 1)
+    nonblock_open - Don't block opening busy PCM devices.
+
+    For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of
+    the card #0.  Similarly, when adsp_map=0, /dev/adsp will be mapped
+    to PCM #0 of the card #0.
+    For changing the second or later card, specify the option with
+    commas, such like "dsp_map=0,1".
+
+    nonblock_open option is used to change the behavior of the PCM
+    regarding opening the device.  When this option is non-zero,
+    opening a busy OSS PCM device won't be blocked but return
+    immediately with EAGAIN (just like O_NONBLOCK flag).
+    
+  Module snd-rawmidi
+  ------------------
+
+    This module takes the options to change the mapping of OSS
+    devices like snd-pcm-oss module.
+
+    midi_map	- MIDI device number maps assigned to the 1st OSS device.
+		  (default: 0)
+    amidi_map	- MIDI device number maps assigned to the 2st OSS device.
+		  (default: 1)
+
+  Global parameters for top soundcard modules
+  -------------------------------------------
+
+    Each of top-level soundcard module takes some general options,
+
+    index	- 0-7 - index (slot #) for soundcard
+                - if not set or -1, first free index (slot #) is assigned
+    id		- user identification for card (up to 15 chars)
+		- default expression is 'card<index>' (for example card1)
+		- value is used for /proc/asound filesystem
+		- this value can be used by applications for identification
+		  of card if user does not want identify card with index number
+    enable  	- enable card (only first card is enabled by default)

+
+modprobe/kmod support
+=====================
+
+The modprobe program must know which modules are used for the
+device major numbers.
+Native ALSA devices have got default number 116. Thus a line like
+'alias char-major-116 snd' must be added to /etc/modules.conf. If you have 
+compiled the ALSA driver with the OSS/Free emulation code, then you
+will need to add lines as explained below:
+
+The ALSA driver uses soundcore multiplexer for 2.2+ kernels and OSS compatible
+devices. You should add line like 'alias char-major-14 soundcore'.
+
+Example with OSS/Free emulation turned on:
+
+----- /etc/modules.conf
+
+# ALSA portion
+alias char-major-116 snd
+# OSS/Free portion
+alias char-major-14 soundcore
+
+----- /etc/modules.conf
+
+After the main multiplexer is loaded, its code requests top-level soundcard
+module. String 'snd-card-%i' is requested for native devices where %i is
+soundcard number from zero to seven. String 'sound-slot-%i' is requested
+for native devices where %i is slot number (for ALSA owner this means soundcard
+number).
+
+----- /etc/modules.conf
+
+# ALSA portion
+alias snd-card-0 snd-interwave
+alias snd-card-1 snd-ens1371
+# OSS/Free portion
+alias sound-slot-0 snd-card-0
+alias sound-slot-1 snd-card-1
+
+----- /etc/modules.conf
+
+We are finished at this point with the configuration for ALSA native devices,
+but you may also need autoloading for ALSA's add-on OSS/Free emulation
+modules. At this time only one module does not depend on any others, thus
+must be loaded separately - snd-pcm-oss. String 'sound-service-%i-%i'
+is requested for OSS/Free service where first %i means slot number
+(e.g. card number) and second %i means service number.
+
+----- /etc/modules.conf
+
+# OSS/Free portion - card #1
+alias sound-service-0-0 snd-mixer-oss
+alias sound-service-0-1 snd-seq-oss
+alias sound-service-0-3 snd-pcm-oss
+alias sound-service-0-8 snd-seq-oss
+alias sound-service-0-12 snd-pcm-oss
+# OSS/Free portion - card #2
+alias sound-service-1-0 snd-mixer-oss
+alias sound-service-1-3 snd-pcm-oss
+alias sound-service-1-12 snd-pcm-oss
+
+----- /etc/modules.conf
+

+ALSA PCM devices to OSS devices mapping
+=======================================
+
+/dev/snd/pcmC0D0  -> /dev/audio0 (/dev/audio) -> minor 4
+/dev/snd/pcmC0D0  -> /dev/dsp0 (/dev/dsp)     -> minor 3
+/dev/snd/pcmC0D1  -> /dev/adsp0 (/dev/adsp)   -> minor 12
+/dev/snd/pcmC1D0  -> /dev/audio1              -> minor 4+16 = 20
+/dev/snd/pcmC1D0  -> /dev/dsp1                -> minor 3+16 = 19
+/dev/snd/pcmC1D1  -> /dev/adsp1               -> minor 12+16 = 28
+/dev/snd/pcmC2D0  -> /dev/audio2              -> minor 4+32 = 36
+/dev/snd/pcmC2D0  -> /dev/dsp2                -> minor 3+32 = 39
+/dev/snd/pcmC2D1  -> /dev/adsp2               -> minor 12+32 = 44
+
+The first number from /dev/snd/pcmC{X}D{Y} expression means soundcard number
+and second means device number.
+Please note that the device mapping above may be varied via the module
+options of snd-pcm-oss module.
+
+
+DEVFS support
+=============
+
+The ALSA driver fully supports the devfs extension.
+You should add lines below to your devfsd.conf file:
+
+LOOKUP snd MODLOAD ACTION snd
+REGISTER ^sound/.* PERMISSIONS root.audio 660
+REGISTER ^snd/.* PERMISSIONS root.audio 660
+
+Warning: These lines assume that you have the audio group in your system.
+         Otherwise replace audio word with another group name (root for
+         example).
+
+
+Proc interfaces (/proc/asound)
+==============================
+
+/proc/asound/card#/pcm#[cp]/oss
+-------------------------------
+  String "erase" - erase all additional informations about OSS applications
+  String "<app_name> <fragments> <fragment_size> [<options>]"
+
+   <app_name> - name of application with (higher priority) or without path
+   <fragments> - number of fragments or zero if auto
+   <fragment_size> - size of fragment in bytes or zero if auto
+   <options> - optional parameters
+	  - disable   the application tries to open a pcm device for
+		      this channel but does not want to use it.
+		      (Cause a bug or mmap needs)
+		      It's good for Quake etc...
+	  - direct    don't use plugins
+	  - block     force block mode (rvplayer)
+	  - non-block force non-block mode
+
+  Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
+           echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
+	   echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
