I've tested pulseaudio-1552abf62820e063e933e54372bec25f8ea2f68a.tar.gz (recent GIT) and discovered it works as intended. There were no docs on building this or even downloading it. The results for me were UNKNOWN.UNKNOWN.UNKNOWN and this is unfortunate. Though dispite this after adding /usr/local/lib to my ld.so.conf file every thing was fine... There may well be other pulseaudio libs that applications might use, but these have not caused problems AFAIK. Thank you for your hard work, this proves that a sink can switch from PCM to AC3 and back at will, even while being used. A point of great contention that I've had with just about every one. I'd imagine this might work for a sink that looked analog but was(or could be) actually digital...
