No audio signal from DisplayPort - ThinkCentre M58, M58p


No audio signal available over integrated DisplayPort. Additionally, certain televisions or monitors may disable analog audio input when the M58/M58p DisplayPort or a DisplayPort to HDMI/DVI adapter is attached.

Affected configurations

Any of the following systems but not limited to the following systems:

  • ThinkCentre M58 (all models)
  • ThinkCentre M58p (all models)

Applies to:

  • Microsoft Windows 7
  • Microsoft Windows Vista
  • Microsoft Windows XP Professional

Note: The system's video is configured to use the DisplayPort.


None. Do not replace any hardware for this issue.


M58/M58p does not support audio over DisplayPort.


In some cases, users can connect to DisplayPort for video and separately connect to analog audio out (PC line-out on front/rear IO port) for sound.

In cases where the television or monitor disables audio when connected via DisplayPort (as well as through DisplayPort to HDMI/DVI adapter), it is recommended to use VGA for video when available.
