--- Comment #13 from Raymond superquad.vortex2@gmail.com 2010-06-06 20:48:21 --- There is a test test_multiple_waveopens() which try to perform multiple waveopens but the current implementation does not support multiple wave open even when the sound card support (alsa sound driver which has multiple subdevices ) because wine only expect there is only one playback device for each sound card
