The is the foundational kernel-level framework for audio in Linux, providing the necessary APIs for sound card drivers to interact with the Linux kernel and user space. It manages audio data flow, PCM (Pulse Code Modulation) interfaces, control interfaces, and MIDI interfaces. Core Components of the ALSA Driver API
