Sound is buzzing from the Left RCA outlet on the Naomi 2 and leaking right channel audio. Plugged both left and right speakers producing same sound. Sound is matching fan hum. Plugged in a separate Naomi 2 and sound is perfect. Definitely something wrong with the left rca on the board but not sure how to fix.
