• Problem: The sound cannot be turned off completely even if you set the Master volume control at
minimum.
Solution: You can still hear some sound even though you have set the Master volume control at

• Problem: When you connect a headphone to your computer while playing sound, a speaker does not
produce sound in the MULTI-STREAM mode at SmartAudio (Windows 7).

to listen to sound from the speakers again, be sure to set those speakers as the default device. The
procedure is as follows:
1. Click Start ➙ Control Panel ➙ All Control Panel Items.
2. Click the SmartAudio icon. The SmartAudio window opens.
3. Look at the playback devices. If you have attached a headphone, the headphone will be automatically
set as the default device, and the icon for that headphone will be checked.
4. To set a different device as the default, just double-click the icon for those speakers. That icon
will now have a check mark.
5. Play any sound by use of a music program such as Windows Media Player. Make sure that sound
comes from the speakers.
For details, refer to the Help for SmartAudio.
