I have Windows XP SP2.
When I play mp3s/wmvs/anything that doesn't use flash, everything works perfectly, but when I play a SWF file or play an FLV file, only the video plays and there is no sound. I reinstalled flash, but nothing changed; still no sound. Also, system alert sounds don't play.
The night before, I tried something out and downloaded K-Lite and installed the lots of codecs profile. Then I uninstalled it and reinstalled some codecs that I had uninstalled, but I don't think that would have anything to do with flash, but it might.
Help?
