RaspberryPi as USB audio extension via LAN

I searched for a solution to provide to my Wadia 151 PowerDAC mini over USB with audio data from the PC with iTunes. He is more than 5m away, needed a USB extension. Since USB Audio is very tricky not work most of the solutions. Now I use the RaspberryPi as a USB host and the Virtual Software Here I can now from the PC to the USB audio device over the LAN to connect as if they were stuck right on the PC. The whole works very well without interruption in 44.1kHz / 16bit, at higher sample rates, it sometimes sounds are skipped, but I have anyway no higher-resolution files. Virtual Here you can also install it on a QNAP NAS, but I have not tried it yet, maybe go there even higher sampling rates.
