My computer seems to be refusing to play any sound files or video files. This means games are silent, and I can't listen to music on iTunes, Windows Media Player, Winamp or various other media players. I also can't watch videos stored on my computer. This happened when I downloaded the latest version of iTunes a few months ago. Whenever I try to play a sound file, it says it's playing it but the progress bar doesn't move and no sound comes out. The same happens with videos.

I've tried reinstalling the old version and about a million other things including re-downloading my sound driver, but nothing works. The funny thing is, I can play audio files in Audacity (an open source audio editor) and watch video clips (with no sound) in VLC Media Player (an open source video player). It seems like only open source things are working, could be a co-incidence though. Please, if anyone knows how to fix this, please let me know :)

Try to reboot your computer.

Uninstall iTunes... Check your sound card and test your speakers.

I've uninstalled and reinstalled itunes many times. And it's not my speakers that are broken because I can hear sounds on the internet (for example on youtube). As for checking my sound card, the driver is working apparently but I don't know how to check the card itself.

If that doesn't seem to be the problem, run HijackThis and post the log file http://free.antivirus.com/hijackthis/

I don'g get what it's supposed to do. I installed it but whenever I try to start it, it just re-opens the installation window. It then tells me there was a "fatal error during installation".

just download Executable (not installer) should work, worked for me :)

(Jul 08 '11 at 18:36) Saakeman Saakeman's gravatar image

and download version 2.0.4 (not the beta!)

Call me stupid, but I can't find the .exe version! The only thing on the link you provided says "Launch HijackThis" and that downloads the installer.

showing 5 of 7 show all

umm how about you look at the mixer settings in windows. since windows 7 and vista changed how the audio actually works.

you can right click on the speaker icon and select PLAYBACK devices. I bet you have it set to headphones that are not plugged in or another device instead of your speakers. It can happen when you forget that windows doesn't change to speakers when you disconnect headphone for example.

I don't know of virus crap or maleware that will turn off your sound. check the settings first.

Nope I can hear sound on the internet just fine, and the mixer says all the programs have their volume up at 32.

your original post is you get NO audio, then you DON'T have the audio settings correct. you can right click on SPEAKERS for example and choose the option to make default. You will need to do this when you have the GAME closed and not running..
you have sound but not in a GAME is a better post title that 'why wont my computer play sound files...'

I don't think you understand ^^ my computer won't play sound or video files that are stored on my computer, but I can hear sounds on the internet (I forgot to mention that part, sorry).

go to the services, and see if Windows Audio Service is disabled

It says "started" and "Automatic".

(Jul 08 '11 at 19:19) wills316 wills316's gravatar image

Try and restart the service.

I've done it... didn't help :/

uninstall the driver for your video card. Then go to the Manufacturers website and download the latest driver for your device.

I've just run into the same problem. Did you ever find a solution?

Make sure your speakers are set as the default audio device. Which OS do you have so I can give you the right steps to make sure it is set how it needs to be?
