Initial fix for APAD iMX51 sound channel noise

11 Feb

There have been reports of sound distortion/pollution on the APAD sound channels.

Here is a visual representation of the noise:

Sound distortion with no cap added


We see that after the initial configuration of the power supplies(at about 25 seconds),  the right channel( lower image ) line thickens after about 45 seconds (just prior to the 00:01:00 minute marker), indicating a tripling of background interference.
