Audio track

Audio support on Linux is currently undergoing a rapid evolution, with a growing expectation on the part of users that everything will work off the shelf with no manual configuration. This is a particular problem at the system integration level, with many diverse audio sources and sinks (both physical and software) in the system which need to be managed together to provide the functionality which end users expect.

The problems are most complex in the embedded world due to both the lack of hardware standards and big developments in both the audio hardware present on embedded systems such as mobile phones and the feature sets supported at the user level.

In this track we want to cover the whole audio stack, from userspace sound servers and interfaces to low-level audio driver architecture. We’ll focus on new audio features for audio production, as well as technology for the classic desktop and cover mobile platforms as well.
