I accidentally deleted my multimedia audio controller. I was removing some other programs and I uninstalled it. I used to have soundMAX but now it won't re-install since I deleted the driver. Can someone tell me how to re-install this driver so my sound will work again! Thanks. I don't know too much about this but I went to belarc.com and got all the info about my laptop, its old so bear with me.
