I just installed the GT220 Graphics card into my p.c, i got it back from the shop and now i have no sound.?

Hmm, unless the old GPU was one of those ATI cards that supply sound through the HDMI interface, in which case you're going to have to take alternative steps.



(edit) No, scratch that - the GT220 has 7.1 over HDMI too. In that case, it's likely driver-related, or "the shop" broke something.|||tell the shop the problem! or call a technician!|||Reload the sound drivers.|||If you had sound before, take it back, it's the shops fault not yours
