I had my 170 apart today to take the hard drive out to test something in another computer. When I got it back together I suddenly have no sound through the speaker. I don't remember for sure, but I'm pretty certain I did power it up today during the part shuffle with it working.
Here's what I've tried:
- Reseating the interconnect cable (multiple times)
- Sound comes through headphones, so I know it's not the sound hardware
- OS volume is on
- Visually inspected the speaker connections and everything looks fine. No obvious damage or bent pins on anything
- I also reseated the processor card and RAM for good measure.
Any ideas on what's wrong, or just how I can test the speaker with my multimeter?
Thanks,

To be clear, the speaker has been working ever since I got it. It only quit after a recent disassembly, although now that I think of that I did just remember something...
When I was putting it back together, I didn't get the interconnect cable seated correctly the first time around. This led to an audio feedback sound (buzzing) from the speaker. Then I reseated it, and now the display and everything else work, but not the speaker. Maybe that killed it
So yeah, how do you test a speaker with a multimeter?
