PC Outputs device failure sound [RESOLVED] Just today, My iPod Touch 2nd Gen 3.1.3 JB won't sync to my computer. I rebooted my PC and iPod. But nothing changed. I have iTunes 9.1, I updated 2 days ago. I solved my issue. Idk what caused it but here are the steps to fix it. 1. Open Device Manager (Start > Run > devmgmt.msc). 2. Navigate to Portable Devices. 3. Select The Apple Device. 4. Uninstall. 5. Then reconnect your device and wait for it to install.
