Very low and tinny volume from internal speakers, but headphones work

[erin66]

I'm getting only minimal sound from the internal speakers of my Latitude E6420. The volume is very low, even though it's set to the highest level. Also, the sound is tinny. It's similar to what you hear from headphones at a distance, like when someone near you is listening to headphones at a high volume, or if you take off your headphones while the audio is still playing.

Whenever I listen with headphones, the sound is great, but with the internal speakers the audio is practically nonexistent.

I've set the internal speakers as my default speakers, I've adjusted the loudness equalization, and I've reinstalled the audio drivers. I've even tried wiggling a toothpick inside the speaker jack, but nothing has resolved this issue.

Can anyone help?

Thanks

Are you using the IDT driver from Dell? If not, here is the link to the Win 7 64 bit driver

Could be the speaker connection is bad (need reseated?). The speakers are connected by a plug in connector according to what I find in the Dell manual. That would be my "best guess" as the problem. Reseating the connector (unplug then plug back in) would be a good first start. Looks sort of complicated though.
Here is the Dell manual and it details how to access it.
