Same here.  It happened after updating my driver from Lenovo's site.  Anyone have an idea?

At least you have ONE speaker, both of mine are dead!!

You might check this thread:

and make sure you're not noticing heating anywhere on the left speaker grille when the computer is plugged into AC power but turned off.

Hi All,

I got my W510 last Friday, the speakers work fine, but the keyboard doesn't work well ...

Anyway, back to speakers, I checked the wiring of W510, see the picture:

As you can see, I marked those wires which tied to CPU in yellow. The cover of those wires could easily melted by the heat from the CPU. That may cause short circuit.

I'm just guessing
