Can you tell me if there are any other upper layer systems that support the Media API? Regarding the usage of pulse audio, our primary restriction at the moment is disk space, so minimising the number of libraries used is of great importance. We only have 8MB available on the final system, so as you can imagine bringing in large libraries is not always possible. The study you mention is what we're conducting at the moment. I'd welcome any alternatives that you can suggest. Given what has been discussed so far, we are currently doing further investigation into using PulseAudio. Regards, Andre
