Noise or no sound comes out of the speakers or headphones
Cause
Solution
Computer may not be detecting the correct speaker/headphone type or output or analog-to-digital auto-sense is not engaged
  1. If you are using digital speakers that have a stereo jack and want the system to auto-switch to digital, use a stereo-to-mono adapter to properly engage the auto-sense feature.
  2. If a stereo-to-mono adapter is not available, use the multimedia device properties to manually switch the audio signal from analog to digital.
  3. If the headphones have a mono jack, use the multimedia device properties to switch the system to analog out. For information, click here to go to Business Desktops d530, d330, and d325 - Setting up Analog/Digital Audio Output.
      note:
    If you set digital as the Output Mode, the internal speaker and external analog speakers will no longer output audio until you switch back to an auto-sense or analog mode. If you set analog as the Output Mode, external digital speakers will not function until you change the output mode back to an auto-sense or digital mode. Click here to go to Business Desktops d530, d330, and d325 - Setting up Analog/Digital Audio Output for additional information.
