|Noise from the DARwIn's speaker echoing network traffic|
|Writer : drewnoakes||DATE : December 13, 2013 | Hit : 9,034|
We have a few DARwIn-OP robots. Some of them make an annoying clicking sound when network traffic flows in and out of the system.
Not all of the robots do this.
The sound occurs even if I mute all the inputs and outputs in software (using alsamixer), so I guess this interference happens in the audio output circuitry.
Has anyone worked out how to stop this happening?
