I managed to make Android build the libaudio shared library (taken from omapzoom.org), which was then put where it should be in /system/ lib/. I also have BOARD_USE_GENERIC_AUDIO set to false, which should make audioflinger use this libaudio instead of the generic libaudiointerface, but I still get the error message:
W/AudioHardwareInterface( 665): Using stubbed audio hardware. No sound will be produced. Any idea what I could be missing here?
