Audio problems in web browsers

[NG41]

Does anyone else have distorted audio when in a web browser?
For example, my systems sounds and mp3s work perfectly BUT once i get on Mozilla and try to view a video such as on youtube or a link on facebook the sound becomes distorted. some of the problems include the music may be really loud and the voices are very quiet or just everything is really distorted. i thought it may be just Mozilla so got on to internet explorer but i experienced the same problem.
does anyone else have this happen to them?

You might see something if you start the Windows Help and Support and type in codecs. Maybe you are missing some or have different ones you might need to try. If you know the type of file being uncompressed, it might help.
