Dear Sir,
 
In my PC, there are two audio interface.
One is the default in motehr board (SoundMax).
Another is USB dungo.
I can use --dacx and --adcx to force the audio input and ouput in SoundMax.
But I can not use --dacx or --adcx to force the input in USB dungo.
I do not know what is wrong.
The codes are as follows:
 adc => gain g => blackhole;
float x;
while( true )
{
     g.last() => x;
     if( std.fabs(x) >= .05 ){
 

              <<< x, "hello" >>>;
 
              }
     1::samp => now;
}
 
Best Regards
Lewis
