T420 / T520 / W520 - No audio when using DisplayPort -> HDTV

Question

On my T420 I can't get any audio through the Display port. The picture is fine, but the computer does not find any audio devices linked to DP.

Answer

  • Ensure you have the latest GPU driver installed
  • Check HDMI audio is setup properly here
  • Ensure the DP -> HDMI converter (dongle) is compatible to stream Audio and Video

Lenovo recommended DP -> HDMI Converter here

 

Customer recommended DP -> HDMI Converter here

 

Please note that customer recommended DP -> HDMI converter is not supported by Lenovo if it does not work and is used at your own risk.
