Help i've lost the use of my speakers!

[Guest]

Please help I have no idea what I have done, last week I had sound and now I
have none!! I have a Acer Aspire 5610Z laptop running Vista and it is telling
me I have no audi output device installed. When I open Device Manager its
showing Bluetooth AV/HS Audio and Realtek High Definition Audio under sound,
video and game controllers. When I open the sound tab it says No audio
devices are intalled under playback but it doesn't let me click configure,
set default or properties I don't know what to do, can they just dissappear
like that?? I'm STUCK!!

Maybe, you did something to it, if you were messing around in that area. I
did something similar trying to set the audio driver to something else on
the HP laptop, which caused all sound to be disabled. It took me a while to
find out what I had done. As I recall, I was in the area of doing something
with the head phone sound when I killed all the sound. The sound area on
Vista is very tricky, and you really have to look hard at the hidden
setting, meaning those settings are not dead in your face and are obvious.
You should just try a few things by working with the settings. You might see
something that is grayed out like I did, which was the sittings for the head
phones that killed the external speakers too.
