Hi Emanuel, This is a common issue I had with multiple ports (the latest being emulators/fceux). The fragment size must be patched to be a power of 2 and the buffer for the fragments must be resized to be at least as large as the fragment size (iirc). This might be the reason why you get a signal. The fragment size is set in the SDL_AudioSpec structure member samples passed to SDL_OpenAudio(). Try to find this call and patch it.
