You'll have to poke at the datasheet for the RF module (microtune 1384 ufc/wfc, or 1385 ufc) to see which pins mean what, but I could get FM audio from an earlier output when probing around the dead component.

Eg. on the 1384wfc, pins 15-18 -- one of those had (muxed) audio, but the final output did not. Thus the failed component was between those two pins, whichever two they were.
