My problem is my laptop use softwer win xp service pack 2 out put sound card is problem,not out put this sound. how can use softwer this problem soft pls tel me this softwer name nd download link

if your question refers to service pack 3 it is that lastest upgrades to the original operating system
for example win xp came out as win xp
later on in it's life a service pack 1 then 2 and finally a service pack 3 was issued where by all the updates were in a pack so that if you had win xp disc and installed it , then you could install service pack 3 and the operating system was up to date
xp is now no longer supported by microsoft and is rapidly falling out of service
win 7 is now up to service pack 1 ( last time I looked ) but with the large amounts of installing up dates , it may be around pack 2
.with the release of win 10 , win 7 will be no longer supported after a period of time

It sounds to me like you requre Win'XP Service Pack 3.
If you are using Service Pack 2 or earlier, there is no
SATA support which is why the HDD is not recognized.

Get Service Pack 3 and your problems will be solved.

Good Luck

With XP home or pro, the sound card may require service pack 2 (at least) or 3 to operate correctly. If your are unable to install the service packs, ( not enough space on your hard drive, say 20 g. or less), then you will need to locate an older style sound card that ran off of win 98, this will still work with your xp set up. This information comes to you from someone who spent hours at a computer store, to finally find out this answer

Windows xp service pack 3 is your problem. SP3 takes a lot of memory to use. You should be able to uninstall sp3 and go back to sp2.

Your soundcard driver is waiting for you
