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"

-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.

+and "Debug" options. To check for memory leaks, turn on "Debug memory"

+Please note that all the ALSA ISA drivers support the Linux isapnp API

Creating ALSA devices
=====================
-Use the /dev/MAKEDEV script to create the nessecary device nodes.
+This depends on your distribution, but normally you use the /dev/MAKEDEV
+script to create the necessary device nodes. On some systems you use a
+script named 'snddevices'.
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.
+The user can load modules with options. If the module supports more than
+one card and you have more than one card of the same type then you can
+specify multiple values for the option separated by commas.
+
+Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed.

+ after loading the module, find out the assigned ALSA sequencer port
+ number through "sbiload -l". Example output:
- Each of top-level soundcard module takes some general options,
+ Port Client name Port name
+ 64:0 OPL2 FM synth OPL2 FM Port
- 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. (all cards enabled for PCI and ISA PnP cards
- as default.)
+ Load the std.sb and drums.sb patches also supplied by sbiload:
+
+ sbiload -p 64:0 std.sb drums.sb
+
+ If you use this driver to drive an OPL3, you can use std.o3 and drums.o3
+ instead. To have the card produce sound, use aplaymidi from alsa-utils:
+
+ aplaymidi -p 64:0 foo.mid

+ ML (see the section "Links and Addresses").
+
+ Note 2: If you get click noises on output, try the module option
+ position_fix=1 or 2. position_fix=1 will use the SD_LPIB

+ the position buffer instead of reading SD_LPIB register.
+ (Usually SD_LPLIB register is more accurate than the
+ position buffer.)
+
+ NB: If you get many "azx_get_response timeout" messages at
+ loading, it's likely a problem of interrupts (e.g. ACPI irq
+ routing). Try to boot with options like "pci=noacpi". Also, you
+ can try "single_cmd=1" module option. This will switch the
+ communication method between HDA controller and codecs to the
+ single immediate commands instead of CORB/RIRB. Basically, the
+ single command mode is provided only for BIOS, and you won't get
+ unsolicited events, too. But, at least, this works independently
+ from the irq. Remember this is a last resort, and should be
+ avoided as much as possible...

+AC97 Quirk Option
+=================
+
+The ac97_quirk option is used to enable/override the workaround for
+specific devices on drivers for on-board AC'97 controllers like
+snd-intel8x0. Some hardware have swapped output pins between Master
+and Headphone, or Surround (thanks to confusion of AC'97
+specifications from version to version :-)
+
+The driver provides the auto-detection of known problematic devices,
+but some might be unknown or wrongly detected. In such a case, pass
+the proper value with this option.
+
+The following strings are accepted:
+ - default Don't override the default setting
+ - none Disable the quirk
+ - hp_only Bind Master and Headphone controls as a single control
+ - swap_hp Swap headphone and master controls
+ - swap_surround Swap master and surround controls
+ - ad_sharing For AD1985, turn on OMS bit and use headphone
+ - alc_jack For ALC65x, turn on the jack sense mode
+ - inv_eapd Inverted EAPD implementation
+ - mute_led Bind EAPD bit for turning on/off mute LED
- irq_mask - IRQ mask (PCMCIA type)
- irq_list - List of available interrupts for this soundcard
+For backward compatibility, the corresponding integer value -1, 0,
+... are accepted, too.
- Note: the driver is build only when CONFIG_ISA is set.
+For example, if "Master" volume control has no effect on your device
+but only "Headphone" does, pass ac97_quirk=hp_only module option.

+Early Buffer Allocation
+=======================
+
+Some drivers (e.g. hdsp) require the large contiguous buffers, and
+sometimes it's too late to find such spaces when the driver module is
+actually loaded due to memory fragmentation. You can pre-allocate the
+PCM buffers by loading snd-page-alloc module and write commands to its
+proc file in prior, for example, in the early boot stage like
+/etc/init.d/*.local scripts.
+
+Reading the proc file /proc/drivers/snd-page-alloc shows the current
+usage of page allocation. In writing, you can send the following
+commands to the snd-page-alloc driver:
+
+ - add VENDOR DEVICE MASK SIZE BUFFERS
+
+ VENDOR and DEVICE are PCI vendor and device IDs. They take
+ integer numbers (0x prefix is needed for the hex).
+ MASK is the PCI DMA mask. Pass 0 if not restricted.
+ SIZE is the size of each buffer to allocate. You can pass
+ k and m suffix for KB and MB. The max number is 16MB.
+ BUFFERS is the number of buffers to allocate. It must be greater
+ than 0. The max number is 4.
+
+ - erase
+
+ This will erase the all pre-allocated buffers which are not in
+ use.
