i have the same exact problem. I think i got this virus from something i downloaded from limewire.
I have a similar problem in XP.
My sound worked fine.
Then I got a vundo virus which Sage5 was kind enough to help me fix.
But after this, sound works fine everywhere except for sound coming from the internet (i.e. streaming video and such). I can play mp3s, video games, movies, etc with sound, but nothing on the internet.
Plus as hkimle pointed out, my audio controls were removed from the tool bar, and they don't reappear if I check them in control panel.
I tried the regedit suggestion, but "wavemapper" already existed in my registry (so I deleted it and added it again ...no change).
Any other suggestions?
I cant heare any audio from the internet, on any of my browsers, but i can see video. I can play downloaded videos and music fine, but nothing works on the internet. also when i goto blogspots my internet browser freezes then crashes. I have used about 9 different virus protection, spyware, malware and other kinds of protectors/ scanners and i believe the virus is gone. I have tried everything that HK did, nothing worked.
i even tried making a new account on my pc, and it still didnt work.
i figured i would have to use system restore, but after waiting about an hour for system restore to finish, it said "system restore failed! no changes have been made to system" this is begining to be very annoying... i downloaded and reinstalled all my codecs, and tried to reinstall drivers but it didnt change anything.
BTW: When i tried to reinstall drivers, it said " devices not found, restart your computer and try installation again"
that didnt work, and when i checked the audio settings it said no audio devices found. I know nothings wrong with the speakers cause regular dowloaded videos and music work.
is this some new virus spreading around?
i dont realy feel like taking my pc to the shop to get it fixed. should i try reinstalling windows?
