How do I install REALTEK HD Audio Manager?

Realtek HD Audio Manager problem - audio doesn't work except for in-manager test after changing default format?

• I was playing around with my Realtek HD Audio Manager and trying out the sound effects for the Speakers tab when I changed the 'default format'. Immediately after this happened, the audio I was listening to simply stopped (even though it was still playing), and I was no longer able to hear any audio from my computer whatsoever except for the speaker test in the Manager itself. I have tried to reset to the default 'default format', but my audio still is gone. I can not system restore -- I haven't remembered to turn it back on since a virus that used it to stay alive had to be removed from my computer. It seems that is the only advice I've seen when I try to google the topic (although I haven't seen anything like my problem, to be fair). How can I fix my sound?

• Answer:

  Make sure you did note mute it in anyway, check your mastersound settings and see if anything is checked off, start all programs, accessories intertainment and then sound controls, I believe, and if that dosen't help you might have to reinstall your audio drivers, trough the Proprietary CD the computer came with or by downloading the software from the manufactures website.
