Question DCHDMI install - lifted pad and unable to find trace.

[d31801]

I have just completed an install of the DC HDMI mod. I've got video with no issues but the audio is crackling. I've checked the audio IC and one of the solder pads is missing. I cannot see where the trace goes so does anyone know where I can find some information on how to find the trace so I can bridge the connection?

I have run a continuity test on all the pins that have been soldered to the audio IC and there are no bridges.

Thanks
