First, what is ALSA; Advanced Linux Sound architecture abbreviation for ALSA, translated into Chinese meaning is the Linux Advanced Sound system (this is my literal translation, may be incorrect); when it comes to the system, it's a bit too much, so ALSA not only includes support and drive for sound cards. ； ALSA has

Andrew Huang bluedrum@163.comALSA is a late audio processing library in Linux, mainly for improvements to the existing OSS libraries. Better performance, support for multiple playback sources, and so on. But correspondingly, increased programming complexity. The old OSS is a standard file IO interface, the device is opened with open, the audio recording is the data IO interface (read/write), the parameters of the device are controlled by IOCTL. They're all system calls. This eliminates the need

Recently in Linux to do the program, a long time did not listen to music, only to find that my Linux system has been no sound, just installed sound card driver, installed a long time to find information on the Internet, feel that this is a more authoritative ALSA, i.e. advanced Linux Sound architecture. It is a good sound card driver, can drive most of the sound card, but also support multiple audio streaming, support multiple sound card and so on. So

First, introduce what is ALSA;Advanced Linux Sound architecture abbreviation for ALSA, translated into Chinese means the Advanced Linux sound architecture (this is Google translation); when it comes to architecture, it's a bit too much, so ALSA not only includes support and drive for sound cards;ALSA has the following

Advanced Linux sound architecture (ALSA) Study Notes Reprinted please indicate the source and the author contact: http://blog.csdn.net/absurd Contact information: Li xianjing Last Updated: 2006-12-19 ALSA is not a new thing that has just emerged recently. It has actually been developing for many years. However, it has not become a proper replacement for OSS names until it is in kernel 2.6.

Kernel version: Kernel 2.6.28.6 compiled by the menuconfig configuration file top6410_3d.config (if you use the old version of 28 kernel or use the default menuconfig configuration file for compilation, the Alsa recording will not sound) File System Version: ubifs in the old version.
