Ho provato a  far riconoscere la scheda di acquisizione video ovviamente non funziona ma è presente come HUB USB
quindi in teoria se una USB-AUDIO compatibile è riconosciuta da morphos
dovrebbe funzionare.
Con il comando da shell di morphos:
USBDevLister
ecco l'output

http://www.google.com/search?q=usb+0x46F4+0x0002viene riconosciuto l'HUB USB di qemu e l'aggiunta eventuale del device USB-AUDIO anche se questo comunque non dovrebbe servire.
In conclusione se la pennetta AUDIO-USB è compatibile con morphos l'audio dovrebbe funzionare
