No Sounds After Nimo Codec Update

HI,
After trying to fix 2 missing audio codecs, (iviaudio.ax, and mpgaudio.ax) with Nimo codec pack, my pc will not play dvds. I uninstalled the pack, only to find now that I have no sound on either windows media player 10, or realplayer. I also have Power dvd 5, but that is unaffected and still plays dvds fine.
I was running Gspot, andnow that wont work either and freezes when I try to find out what codecs are installed.
I did a sysytem restore but that didnt fix the problem either. Any ideas or help please !!!!!!!!!!!!!!!!!!

sounds like you nered to find out what audio card you have (viaaudio obviously) like exact model then re install the audio device
