Linux ALSA Audio Driver - Release Notes
Version: 01.00.0500, General Release
Release Date: July 21, 2005

--------------------------------------------------------------------------------
PRODUCT INFORMATION  
--------------------------------------------------------------------------------
Developed under Linux Kernel 2.6.11

This product includes:
- os_inc.c
- os_inc.h
- amd_geode.c
- amd_geode.h
- configure.ac
- Makefile.in
- README (this file)
- AUTHORS
- COPYING


Features
--------
- Playback of audio files in all formats including MP3 files
- Recording of audio files in all formats
- AC97 interface
- Compatible with AD1819 codec
- Compatible with 2.6.x Kernel

Applications Tested:

Playback:

- XMMS
- gmplayer (1.06pre-RPKM-3.4.2 over OSS )
- noatun
- aumix
- XINE player
- alsaplayer
- QuakeII
- aplay
- sox play

Recording:  
- arecord
- sox rec


Dependencies
------------
- Linux Kernel 2.6.11
- ALSA rel. 1.6
- kernel patch v01.01.0302 or later (AC97 support,pcm_oss.c patch).
- To support OSS-based applications which use MMAP (like quake2) it is
  necessary to patch the file pcm_oss.c in the kernel tree at
  "/linux-2.6.11/sound/core/oss".   Without this, the application is not
  able to open the driver correctly!


Functional Changes
------------------
- Bug #2825:  MIC Mixer at 0, MIC not muted [ALSA]
- Bug #3761:  linux 2.6 l-16.001-036 ALSA garbled playback of recorded cd,
  line, mic files
- Bug #2707   README corrections [ALSA]


Defects Corrected
-----------------
Issue: PBZ#2825 MIC Mixer at 0,  MIC not muted [ALSA]
Description:
The Mixer sliders in alsamixer and aumix for PCM, LINE, CD, and MIC devices
move audio consistently down from 100 to 50 (although 50 drops the volume to
silent).  At 49, the volume jumps back up to Full volume and then keeps moving
down as you move to 0.  
Resolution:
Corrected an ALSA layer probing problem.

Issue: PBZ#3761 ALSA garbled playback of recorded cd, line, mic files
Description:
At 12000 Hz, files recorded using arecord/ALSA and played back with a
play/ALSA have "garbled" playback. Playback was not garbled during play/OSS
emulation playback.
Resolution:
Under any circumstances arecord chooses non-integer values for buffer-size and
period-size. This leads to a moving interrupt pointer which was still not
implemented for capturing.

Known Errata
------------
PBZ#5989 MPLAYER - A/V Sync is off, Video ahead of Audio
  Notes:   We recommend that builds of MPlayer use ALSA by default (as opposed
           to OSS).   If one needs to use the OSS-plugin, then we recommend this
           driver be compiled with the setting DEFAULT_DMA_BUFFERSIZE=0x10000.

INSTALLATION INSTRUCTIONS  
--------------------------------------------------------------------------------

Kernel Configuration
---------------------
- In order to use audio drivers under Linux, the ALSA
  modules have to be installed.  

  How to build the Kernel with the ALSA installed:

     1.  Type: "cd /usr/src/linux"
     2.  Type: "make menuconfig"
     3.  Select "Loadable module support" and un-check
         "Module versioning support" if set.
     4.  Select "Device Drivers" option
     5.  Select "Sound"
     6.  Select "Advanced Linux Sound Architecture"
     7.  Select "CI Devices"
     8.  Check "AC97" (press M to include as a module)
     9.  From the main menu select exit, when prompted to save config,
         say yes."  This will separate the enabling sound step from the
         exit/save step and the build step.
         Save configuration and exit

     Build kernel/modules and install as described in README.kernel.txt


Compiling and installing the driver (standalone):
-----------------------------------------------------------------------   
- After unpacking the tarball, which contains the files listed above
  in a plain directory,  run :
  1. autoconf  (builds .configure)
  2. ./configure --with-kernel-path= "your path to the kernel sources"
  3. make install

    You need to have root permissions to build and install the driver.
  Follow the instructions of the install script
  The built driver will be located in the local directory as well as in
  /lib/modules/$kernel-path/kernel/drivers/misc
  (Make sure that module support is enabled in the kernel configuration)
         
  !!!! Additionally it's required to build the kernel with enabled
  ALSA - ac97 driver.  When the ac97 driver is not available, the amd_geode
  audio driver cannot be loaded!!
  (see above)

- run alsaconf  

The OSS emulation documentation can be found under
$(KERNELDIR)/Documentation/sound/oss or on the internet at
http://www.alsa-project.org/~iwai/OSS-Emulation.html

到 www.kernel.org 下载内核源码编译或编译alsa老出错。还有就是我用kernel-source-2.6.8编译内核时没有发现AC97模块选项，且上面帮助中总感觉里面的几个文件没用到。
