Here are a couple of links that summarize the audio chip issues.

Putting a resistor in series with the headphone jack can protect against the chip being shorted out. In my case I put two series resistors, one for the right and one for the left channel on the headphone jack. That way I can use either mono or stereo speakers and headphones with the uBITX.
