Hi All!
This is an initial public announcement to the AGL community regarding
the work that we at Fiberdyne Systems are currently doing on a new
dynamically configurable “virtual” sound card for AGL.
In April at the Karlsruhe F2F, we showcased the beginnings of a dynamic
sound card that could be configured at runtime to accept a given number
of audio streams, which would provide a standardized interface to play
audio. This idea was further developed in June at the Lorient F2F, and
we have since started development on the proposed solution. The
repository will be available at https://github.com/fiberdynein the
coming weeks.
Presently, our goal is to provide a configurable top-level “virtual”
sound card with a simplified integration path that unifies the audio
architecture for any given bottom-level sound driver. The new driver
will interface directly with the 4A HAL, in place of the current default
loopback card (snd-aloop).
We can achieve a level of configuration using sysfs module parameters
when the driver has modprobe called. We currently have a basic API which
would configure:
*
Number of playback streams
*
Per-stream names
*
Per-stream channel width
However, we would like to take this opportunity to reach out to the AGL
community for any additional requests for API that may be suitable for
configuration through a sysfs interface.
We will be attending the Face to Face in Santa Clara in September where
we can continue the discussion around potential API and use cases.
All feedback is welcome.
Kind Regards,
James O’Shannessy and Mark Farrugia.
