Message:

Audio: More locking needed to avoid debug assertions when draining a stream on stream disable. This debug assertion will happen because EMT and the mixer's async I/O thread work on the same circular buffer. There can be situations, if no locking is being used, that the async I/O thread just has consumed the remaining data just a tad before EMT looks for remaining data within the same buffer when disabling the stream [Doxygen fix]. bugref:10354
