<p>add proposal</p> <p><b>New page</b></p><div>; Summary : Complete ALSA hardware scenario/use case support in alsa-lib and salsa-lib<br /> <br /> ; Proposer : Liam Girdwood<br /> <br /> == Description ==<br /> Modern mobile devices are increasingly required to provide a rich set of<br /> audio functionality required by today's applications. ALSA currently<br /> lacks a portable and high level API to configure audio hardware function<br /> and signal routing.<br /> <br /> e.g. there is no portable method atm to configure the audio hardware to<br /> make a &quot;handset gsm phone call&quot; or &quot;handset voip phone call&quot;, etc.<br /> <br /> This purpose of this project would be to complete the ALSA scenario<br /> manager API and get it accepted upstream in alsa-lib and salsa-lib. The<br /> code is nearly ready for upstream, with some work required on it's file<br /> format as the main piece of outstanding work.<br /> <br /> == Related Work ==<br /> More Info:<br /> * http://www.slimlogic.co.uk/?p=40<br /> <br /> API header:<br /> http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=include/ascenario.h;h=b1395515b035629d09cd9b3d3a224743053aa159;hb=ascenario<br /> <br /> Development branch now hosted as alsa-lib branch here:<br /> * http://git.alsa-project.org/?p=alsa-lib.git;a=shortlog;h=ascenario<br /> <br /> ; Scope : This project will probably take between 2 - 4 weeks.<br /> <br /> == Comments ==<br /> <br /> [[Category:Project proposals]]</div>
