* implement inner loops using liboil * drop "typeid" stuff * add support for channel maps * add support for seperate volumes per channel * add support for hardware mixer settings (only module-oss implements this for now) * fix a lot of types for _t suffix git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@463 fefdeb5f-60dc-0310-8127-8f9354f1896f
