I was working on this laptop for a friend, Ive downgraded her laptop to XP-pro, but yes HP has become the comedian these days, no drivers for xp, so sorry they tell me. So my friend will not have any sound. Ive installed so many UAAs let me see Sp.32646 UAA, with Coexant sp.34200 driver. and a few others, but non get the sound to work. The only sound that is there are the preinstalled xp sound codecs and other stuff. I really need some help, im all out of solutions for my friends sound, can anyone help me?
