i just installed a new gfx card (gts 450) and it installed its "nvidia hd audio" in place of my older "realtek hd audio"
now when i check under my sound devices all that's there is my headphones (usb)
iim guessing my sound card has been uninstalled somehow?
how can i get my speakers working/detected again?
I reinstalled realtek drivers, and it only shows up in control panel -- > uninstlal programs. but there is nothing under device manager and there is no hd audio manager in control panel.
