How to specify 'device name' of audio sink in gnu radio (Windows)


#1

How to specify ‘device name’ of audio sink in gnu radio in Windows? I tryed a lot variants (for example HW:1,0) but always got a message:
‘INFO: Warning: waveOut device ‘HW:1,0’ was not found, defaulting to WAVE_MAPPER’

WAVE_MAPPER is ok, but I need to use three cards simultaneously.
