For Windows: On the bottom left of your screen, select the "Start" menu. Select "Settings" then "Control Panel". In the window that opens, select the "Sounds and Audio Devices" icon. (If you don’t see a choice called "Sounds and Audio Devices," choose the "Switch to Classic View" option in the panel on the left of the window, and the left. Select the "Audio" Tab at the top of the "Sounds and Audio Devices" control panel window. Under "Sound Playback," choose your internal sound card as the default device. This varies by computer but should not be set to "USB Audio Codec" or Under "Sound Recording," select "USB Audio Codec" for your default device. Check the box titled "Use only default devices". Click "Apply"...then "OK". Hope this helps.

The solution is probably pretty simple the codec is the format try downloading only mp3 formatted songs and they should work. Go to www.limewire.com for free downloads. use only the mps and have fun. Thanks

As it is recorded, the format may not be able to be read by itunes. You have to change the format of the recordings so that they can be played using your itunes software.

Hi,

If you are using Windows XP, pls try:

• Goto Start, Control Panel;
• click on Sounds and Audio Devices;
• inside the Sounds and Audio Devices Property box, click on Audio tab;
• on the Sound playback Default Device, select another device other than what is currently displayed or one that is not a USB;
• click Apply, OK.

When you connect the devuce to the computer is it detected by the computer.if it says usb problem.replace the usb wire or load the drivers again of your device in your pc.
