• 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).
Solution: Once the headphone is attached, the streaming is automatically redirected to it. If you want
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.
