level just like the direct sound control panel app. More work on the full duplex interface so the compile warning is no longer generated. Full duplex interface is still stubbed out. Moved full duplex mixer reset fix into wineoss driver where it belongs. Added some more locking fixes. Capture and full duplex are now stable.
