Audio Stack Improvements
Contact: Christos Margiolis <christos@FreeBSD.org>
The FreeBSD audio stack is one of those fields that does not attract the same attention and development as others do, since it has been left largely unmaintained, and, although high in quality, there is still room for improvement — from lack of audio development frameworks, to missing userland utilities and kernel driver-related bugs. This project is meant to touch on all those areas, and as such, is more of a general improvement project, than an implementation of a specific feature.
Important work since last report:
-
Several sound(4) fixes.
-
Improved and added sound examples.
-
virtual_oss patches.
-
Gave a talk at the 09/2024 DevSummit in Dublin, Ireland.
Future work includes:
-
More bug fixes and improvements.
-
Finalize and commit of audio(8) and mididump(1).
-
Implement a generic MIDI layer, similar to pcm/, and improve/modernize the MIDI codebase in general.
-
Implement a bluetooth device management utility.
-
More virtual_oss patches and improvements.
-
Attempt to implement an snd_hda(4) pin-patching mechanism.
-
Investigate SOF/DMIC support.
You can also follow the development process in freebsd-multimedia@, where I post regular reports.
