Installation and configuration of the Sound Card Driver in Linux (1)

Over the past few years, although Linux has been invincible in the global server market due to its open and free features and powerful performance, it has occupied more and more market share, the multimedia features of Linux have never been quite satisfactory. For example, the built-in sound card driver in Linux supports very few sound cards. Most of the popular sound card products in the market cannot obtain system support.
This situation is rapidly changing. Many vendors see the trend of the times and actively participate in driver development. Some organizations and individuals have also begun to make some useful explorations.
The software we introduced today is a Sound card driver package-ALSA, full name of which is Advanced Linux Sound Architecture. It is one of the software under the GNU flag. As the name suggests, it can drive sound card devices in Linux.
It supports most popular sound cards. Modular architecture. Supports full duplex, digital audio, and other sound card features.
You can download the latest software packages from the FTP site to which the http://www.alsa-project.org belongs. If you are interested and have enough capabilities, you can join the development team. Show your talents to the world.
The following describes in detail all the installation and configuration processes and precautions of ALSA, and provides a list of supported sound cards.
Check whether your sound card is supported by the list before installation. In case you do not need to be busy.
I. hardware and software environment requirements.
The author's hardware environment: Sai Yang 366 CPU/Microstar 6199va motherboard/128 MB kingmax memory/10.2GB Gold Diamond 2 hard drive/8X CDROM/WINFast L2300 graphics card/Yamaha 724 chip sound card
Hard Disk partitioning and operating system software: Windows98 + Windows2000 + BluePoint1.0 (blue point Chinese Linux, fully compatible with Redhat ). Use the LILO starter.
ALSA Requirements for the Linux software environment: no special Linux version is required, but the kernel version is later than 2.2.x. If your Linux kernel is earlier than this version, recompile the new kernel. The kernel version of BluePoint1.0 is 2.2.13.
2. download the software.
The latest version of alsais 0.5.9b. the full file name is alsa-driver-0.5.9b.tar.bz2. Adopts the new bz2 compression format, which occupies less space. In addition to this, the following software packages are required for normal operations:
Alsa-utils-0.5.9a.tar.bz2 ---------- utility package
Alsa-lib-0.5.9.tar.bz2 ------------- compile library files required by the utility
If you use the software downloaded from the Windows operating system, copy it to the Linux system.
First, use the root user to log on and start the installation process.
1: Load Windows partitions containing this file in Linux,
Enter the following command:
"Mount-t vfat/dev/hadx/win98". "x" in hdax is the hard disk partition Number of Win98. If you have any questions, please consult other familiar friends.
2: In the downloaded directory, copy alsa-driver-0.5.9b.tar.bz2 and the other two files to a subdirectory,
Enter the following command:
"Cp alsa-driver-0.5.9 */root"
3: Decompress the file.
Enter the following command:
"Bzip2-dv alsa-driver-0.5.9b.tar.bz2"
When using the “ls”command, only alsa-driver-0.5.9b.tar is available in the front directory, indicating that bzip compression has been removed.
Enter the following command:
"Tar vfx alsa-driver-0.5.9b.tar"
The program automatically generates a subdirectory named --- alsa-driver-0.5.9b.
Repeat this step on the other two packages to uncompress. Run the "ls" command to view the directory.
If you are not familiar with the command line, you can view help information and books. You can also start the X-Window environment, select the corresponding compressed file in the file management program, and select the decompression command in the File menu.
3. Install the driver file.
1: enable sound card support in the kernel.
In most cases, this step can be ignored, because the default status of all Linux distributions supports sound card devices.
2: run the script.
Enter the following command:
"./Configure"
If your sound card belongs to the ISA plug-and-play type, enter the following command:
"./Configure -- with-isapnp = yes"
Enter the following command:
"Make install"
Note that this step takes a long time. Please wait. If everything is normal, the program will finally prompt that the module has been compiled successfully! It also warns that the default sound card status is mute. You need to use utilities such as amixer to adjust the volume.
The amixer-0.command is included with alsa-utils-0.5.9a.tar.bz2 and can be used only after compilation.
If the make command cannot be executed, you need to find the Linux installation disk and install the file packages related to development and compilation into the system. For more information, see the software manual.
Enter the following command:
"./Snddevices"
The script automatically creates a sound card device in the "/dev" directory.
4. Install the library files and utilities.
The corresponding library file can be compiled only after you find the corresponding library file, such as your amixer.pdf. First install alsa-lib-0.5.9.tar.bz2.
Go to the appropriate subdirectory alsa-lib-0.5.9,
Enter the following command:
"./Configure"
Enter the following command:
"Make install"
After these two steps are done, return to the upper directory, enter the alsa-utils-0.5.9a subdirectory,
Enter the following command:
"./Configure"
Enter the following command:
"Make install"
Note: If the "./configure" error occurs in the preceding step, you may need to use the "-prefix" parameter to specify the path.
For example, when installing the library file, try to use "./configure-prefix =/usr/include/linux"
When installing the utility, try "./configure-prefix =/usr/include/sys"
