Re: streaming output with usb-dux?

Hi Per,

it should work. The streaming output is supported. I've tested it successfully 
with ao_waveform. I've never experienced any problems with it.

But in qt-wave there seems to be similar problem. I've noticed it recently that 
streaming only works for a while and then I have to restart the program. You can 
ask Tao for help or a bug-fix.
