什么是ALSA？我阅读了*页面,但无法理解.我所理解的是,它是内核中与声音有关的模块.

如果你不在内核中包含它会发生什么,这是否意味着扬声器不起作用或什么.我问,因为我正在尝试安装Linux版本,但我不知道内核是否应该包含ALSA

解决方法:

ALSA代表高级Linux声音架构,如果你真的很好奇,我鼓励你在他们的project website周围逛逛.具体来说,我会看一下“I’m new to ALSA pages & tutorials.

ArchLinux维基可能最好地描述它.

The Advanced Linux Sound Architecture (ALSA) is a Linux kernel component which replaced the original Open Sound System (OSSv3) for providing device drivers for sound cards. Besides the sound device drivers, ALSA also bundles a user space library for application developers who want to use driver features with a higher level API than direct interaction with the kernel drivers.

该图还有助于理解各种组件ALSA,JACK等相互适合的位置.内核.

最后一个节选 – How it works: Linux audio explained：

When it comes to modern Linux audio, the beginning is the Advanced Linux Sound Architecture, or ALSA. This connects to the Linux kernel and provides audio functionality to the rest of the system. But it’s also far more ambitious than a normal kernel driver; it can mix, provide compatibility with other layers, create an API for programmers and work at such a low and stable latency that it can compete with the ASIO and CoreAudio equivalents on the Windows and OS X platforms.

所以底线是ALSA是提供其他音频软件组件访问内核的层,所以要回答你的问题,是的,你需要它.
