From dd10c982414dfa8fbb9aeeeae61c68e4a6f081cc Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Fri, 27 Jan 2006 16:25:31 +0000
Subject: Mega patch:

* 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
