Which sound driver should I install on my laptop? [closed]

Question

A friend of mine fragmented my laptop and now there is no sound in it. People say that I need to install a sound driver on it? Where on the internet can I find this sound driver and how can I know which driver exactly I need to install on my laptop? Where o the laptop should I check specifications?

I am using windows XP on my laptop.

So, after running devmgmt.msc command I got this:

I am sorry I forgot to mention that my laptop is Chinese and I don't read Chinese. However, choosing the line that contains the words "sound card" - as I could understand in Chinese - and the yellow question mark, I got this:

Among four of these tabs only the third one contains the dropdown menue, so I chosed that one:

Among all these menue lines only some of them show some data when I choose those lines. So, bellow are only those menue lines that show some data:

Here is data from the above image:

PCI\VEN_1106&DEV_3059&SUBSYS_43431509&REV_60\3&61AAA01&0&8D

So, does it provide any useful info or I have opened a wrong tab?

Answer 1

Ok, go to start, go to run OR press windows key and R to open run, then type in devmgmt.msc and press ok, this should then start the device manager, you can open it several other ways but this way is the same whatever custom stuff you have running, if you know how to open it anyway, ignore the above.

next find the sound card, it will probably be the one with the question marks on it.

next, right click and go to properties, then to the details tab

from the dropdown select hardware id's, then right click, select all and copy

then edit your answer above by clicking edit then paste the hardware id's below your question.

This is going to be the most accurate way of someone finding a driver for your sound card, another way is edit your question above and add the exact make and model number off the bottom of your laptop into the question box above, so everyone can see it, this is less exact as there are sometimes more than one available for each model, but this isn't a problem as at least we can tell you which ones to try then.

At the moment with none of this info we are just guessing, so help us out with the above and we can help you.

EDIT >>>>>>

By the way, there is an alternative, I think its odd that defragging your hard drive caused your audio driver to vanish, so you could always do a system restore, if you go to start, programs, system, then I think its system restore on Windows Xp, run that and roll it back to before your friend had it, this should then undo anything they did to it, don't worry it wont loose any files / data it only restores system files / settings etc.

Other than post the info needed above..........
