      No audio signal from DisplayPort - ThinkCentre M58, M58p

      Symptom

      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.

      Solution

      None. Do not replace any hardware for this issue.

      Limitation

      M58/M58p does not support audio over DisplayPort.

      Workaround

      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.
