Did you check the audio connectors? Can you confirm you're not getting a mono output because one is broken?
If either of those caps are bad, you won't hear anything for the side. I would be more inclined to swap in from the good side than short it out since it is a direct line to the Op Amp.
If the cap is good, start tracing forward from pins 33/34 on Paula with a scope or cheap analyzer.
