Hi, I am trying to access USB MIC, UA MIC and USB HP UA HP , together at the same point of time and to transmit different waveforms in diffrent output devices. Presently I can access either of the one Input devices or either of the one output devices through appliction whereas I want both the input and output devices to be accessed at a time. My application code is running successfully when device is chosen as default. If instead of default I am putting "plughw 0:0", I am getting the error as ALSA...
