Since 145u2 soundsync patch does not work, probably caused by this
Create a new device_mixer_interface, derived from device_sound_interface, which mixes all its inputs to a single output stream. Redefined the SPEAKER device to use this and remove the duplicate underlying logic. The main purpose of this new interface is to allow device-ification of an entire sound board, which can itself become a mixer of all of its sound components to a single output stream. This stream can then be routed by the device's owner to the appropriate speakers. A real-life example will show up soon. [Aaron Giles] "
Any fix for this is available?
