• 使用 ALSA 音频 API [equalarea.com] 的教程 2002莉>
• 深入了解 ALSA [volkerschatz.com]
• ALSA API - Aquiles Yanez 提供的带有源代码的示例程序 2005
• ALSA 声音编程简介 |Linux Journal(pg3 带有示例代码) 2004

• ALSA Programming HOWTO v.1.0.0 [alsamodular.sourceforge.net]
• A tutorial on using the ALSA Audio API [equalarea.com] 2002
• A close look at ALSA [volkerschatz.com]

请注意，其中一些是旧的，同时 API 可能已更改...您也可以查找 aplay.c(命令行的源 arecord 和 aplay)，但对于初学者来说，这不是最容易阅读的...

Note that some of these are old, and API may have changed in the meantime... you can also look up aplay.c (the source for the command line arecord and aplay), but that one is not the easiest to read for starters...
