I have been using my XT Pro for years now, and the other day i suddently didn't have any sound over USB(been using the Pod as a soundcard when i record). When i start the unit, it says "Standard model set loaded", and my add-ons are gone! All drivers are updated, and everything seems fine in the Monkey, but my metal pack add-on won't work, and i can't record over USB. I can see activity in the windows sound mixer when i play music, but i still don't get any sound through the monitors via XLR or via the headphones output. I have been searching around, and found some talk about a chip that needs to be changed(containing the licenses)?! Do i give up? Do i repair it? Do i get the new HD Pro? Any ideas..?
