SX10 with external speakers

Anthony Thomson

I'm trying to troubleshoot an installation with SX10 and NEC V-series displays.  The audio is very tinny and unnatural sounding, and we're trying to definitively determine the root cause.  My thought is the built-in speakers on the NEC displays, but I need to connect alternate speakers to see if it makes a difference.

This is the problem.  When I hook a pair of computer speakers up to the SX10's audio out port, I get no audio from them at all.  The speakers work when connected up to a computer.

Is there any reason that the SX10 does not send audio out the audio out port, like for instance it is already sending audio via HDMI?

Any other thoughts or suggestions?

This could be related to the routing of the sound. For SX10 devices, it exists a experimental setting that allows to choose the behavior of the sound routing.

If your endpoint is running TC software, you need to navigate to Configuration --> System Configuration --> In the Search Bar, type "routing", the result should be as below:

The options under this settting are:

  • Split
  • HdmiAndLineOut
  • LineOutOnly


I would test first with LineOutOnly (If you will use the Speakers), and verify the results, otherwise if still does not work, then use "HdmiAndLineOut", to send the audio to both, line out and HDMI.

Note: Line Out refers to the audio port you mentioned.

It was set to Split.  I'll give it a try with LineOutOnly and HdmiAndLineOut.
