I do 2 layer analog audio boards with audio traces on top and power + ground on the bottom. The entire audio path treats bottom layer like ground plane. When there is an on board power supply I lay it out on that same plane layer but with it's own ground trace or star ground and then join that to the ground plane at one point only (underneath main filter caps). Until now this has made more sense to me than to have the power supply ground tap into the plane at each point like the audio path, but maybe this is not the best way to go about it?? What do you think is best in this situation and why?
