Speaker Problems
Check the following problems to see the possible cause and solution.
No sound from the speakers.
Check that the system power is on.
Check that the system AC power adapter and AC power cord are connected to the power
source and the back of the system unit.

Sound is only coming from one speaker.
Balance the speaker output by adjusting the balance in the sound software (see the
Microsoft Windows Multimedia online help).

the volume through system software (see the Microsoft Windows Multimedia online help).
