ASoC: Supporting Audio on an Embedded Board, Alexandre Belloni, Live Embedded Event 2020
Channel: Bootlin
Date: 2020-12-03

ASoC, which stands for ALSA System on Chip, is a Linux kernel subsystem created to provide better ALSA support for system-on-chip and portable audio codecs. It allows to reuse codec drivers across multiple architectures and provides an API to integrate them with the SoC audio interface. This talk will present the typical hardware architecture of audio devices on embedded platforms, how to integrate the audio codec and processor audio interface using device tree. Examples, common issues and debugging tips will also be discussed.
