Are the battery terminals dirty?  If an invisible film of corrosion has

The corrosion from alkaline batteries is hard, tenacious and incredibly
difficult to remove if you use conventional organic solvents and
cleaning agents.  The magic substance, which works wonders, is water: a
slightly damp cloth or cotton-wool bud softens the corrosion and wipes
it away.  Clean the terminals on both the battery and in the device,
then make sure they are completely dry before putting the battery back
in.
 
 

No, the terminals on both the new batteries and the old ones (when i put
them back in) seem reasonably clean.

The corrosion is invisible, so a clean-lookig terminal may still have a
semi-insulating layer which is too hard to rub or scrape off without
damaging the plating.

But still no sound.

I thought the problem was fizzing noises, not no sound at all.
