Hello this is my first time here

i have a problem with my Sound.
Ok so i have a custom built PC, and recently its been losing a lot of hard drive space, i found out that windows xp gets a lot of security updates which are not needed and take up space, so i carried onto delete them, i also deleted a few other things i thought i didnt need and in the process accidentally made me lose sound. heres a Belarc Report.
i have a question mark over Multimedia Audio Controller, and i have looked around to see if i have a cd for it but cant find it, heres a belarc report and my device manager.

I remember recently deleting SigmaTEL sound from my PC, and since then the sound aint worked, or maybe i have too many sound controllers and they are conflicting??
Still been trying for days now to get it back but no luck.. starting to miss my music, if anyone can help me to find this SigmaTel sound for my system then that would be great.
Also do you think i should just make a system restore, uninstall all my audio controllers and start over? If it may make it worse ill leave it alone but it was just a suggestion from a friend.
Also my sound device is actually a Phillips PSC724 and i did download the drivers for it twice, and installed it properly, but it did nothing, help me please
