Hello, people

i've just formatted my windows vista and downgraded it to windows xp sp2 , although i have no drivers for windows xp but i managed to download most of them using the internet, but a bad thing occured ,

the sound is working normally and i can hear voices and so on but the thing is that when i listen to songs or such things or even normal sounds the sound quality sux ! i mean my laptop is Toshiba a300 , the voice was very high quality and really clear when i used the normal vista which was installed when i bought the laptop , but now after i formatted , and though the sound drive is working , the sound quality is so bad ,,

do any one know what is the problem ? or how to solve it ?

note that i took info from windows vista, by using the command Dxdiag.exe at run , and the sound drivers were the following :
Conexant High Definition SmartAudio 221
Digital Output Device (HDMI) (High Definition Audio Device)
and i downloaded the first one and installed so the voice worked but in that bad quality i told u guyz about ,, the 2nd thing i didnt know where to find , but i dont know if its wats causing this problem,, or is it something else ..

so please help me ,, thanks all

bye
