All the sudden outta no where my laptop speakers sound like crap ! They dont even get very loud so i dont know how they could possibly be blown.But when i plug in my portable speakers or my head phones they sound perfectly fine.What could it be ??
Based on your external speakers sounding OK, your sound card is OK. You probably have a loose wire or connector in your internal speaker wiring. It's unlikely that both speakers would fail at the same time. But if you only have one internal speaker (common on old laptops), the one speaker could have failed and your sound would be fuzzy and quiet. Several laptops, including Dell 700M units, run speaker wires thru the LCD hinge area causing them to flex and eventuall break. You'll need to remove the upper case plastics and keyboard and look at the wiring and speakers to see what needs repair.
One thing about speakers is they have magnets in them. I had a laptop that all of a sudden started sounding terrible. I bought replacement speakers and when I took it apart to replace them there was a used staple sitting on the cone attracted by the magnet. It did trash the speaker on mine but yours might still be good by just removing the debris.
