USB Audio Device
I have a FX2LP design with a set of descriptors to create a USB audio device. The device implements a speaker, so I have a USB streaming input and a speaker output. The device is recognised by Windows as a USB audio device. However when I open media player and play an mp3 I dont get any data coming out of the FX2LP. I should mention that the FX2 is connected to an FPGA. I have a program monitoring the data coming into the FPGA, but nothing happens. Does anyone have any thoughts? I have attached the file if anyone can see any problems.
