Why does the sound often cut off, even for a few seconds sometimes ?

Check your bandwidth indicator (coloured band next to your name). A red band indicates a bad connection. If that happens, make sure to be the only Internet user on the network. If you are using a wireless, satellite or USB mobile connection, plug your computer to your modem/router using the Ethernet cable provided. Also, avoid downloading when you are online on Via. Spyware, or other system malfunctions, can also create bandwidth problems. Contact your computer technician about this issue. Your Internet service provider may also be experiencing technical problems. In doubts, contact them for further investigation.
