Serious sound problem

I had my speakers plugged into the lineout jack which is stupidly positioned on the front of my Sony FE590, When I stood up it ripped my headphone jack down, Now it dosent work and its disabled my onboard speakers as the computer seems to think there is still a plug in the jack, I checked the mobo and there are no broken solder joints but the motherboard is cracked on the corner the line out jack is on. Can anyone suggest anything to get the jack working again? or at least the onboard speakers?

 

Dang, I don't think there's a way in software to disable your crippled headphone jack (so as to force the onboard speakers to work). I'd call your reseller or Sony's tech support. Otherwise, you could always buy a USB speaker set like the Logitech V20's.

 

Since you can't see any broken traces on the motherboard, maybe something broke inside the actual jack/jack mount. If you're lucky you can find parts on ebay, or from a wholesaler who you can get a local shop to order from.

 

Im considering trying to chop off the jack to see it it enables the sound output.

 

That will probably do it. When you plug the jack in it completes a circuit. So cutting off the jack should give you an open circuit like when the jack is not plugged in.

 

Sounds logical to me, just make sure you have a pretty good handle on the effects of your actions (in other words, don't screw up your whole laptop for the sake of sound). It should probably be a rather easy removal, but a slip can cause some serious damage.

 

I removed the sound jack, Laptop still works fine but the speakers still dont work >.<

 

You sure your sound card is not damaged---does it show up properly under Device Manager? Do you have any unusual events in the System Event viewer?

 

No, Everything appears good in the device viewer and it still detects everything. The sound dosent work even when booting, It used to make a noise when booting up which it no longer does.

 

Did you try unplugging the laptop and removing the battery? Leave it that way for a few minutes. If your sound card uses a PCIe slot, try to gently remove that too. I am hoping that whatever register is storing the status of the speaker/headphone jack status gets reset this way.

If that doesn't do it, you may have to bite the bullet and bring/send it in.

BTW: Make sure you're properly grounded. Static electricity will screw things up mighty quick on an exposed motherboard.

 

Try removing the device from device manager and rebooting. You could disable onboard audio in the BIOS and add a second reboot in the middle, but it probably won't be any different. Windows may be getting mixed signals from the device and isn't handling the situation properly, if the driver doesn't reload you know the device itself is hosed.

Do you have any sort of accidental damage protection?

 

Ive removed power, It has very minimal bios options, dosent even mention sound. I dont have any damage protection but im upgrading in a month. Now I just need to find a 15.4" machine with 4 hours battery and a 8600GS-GT
