Hi,

I have a laptop on which Vista Home Premuium, Service Pack 2 is installed.
Sometimes after a reboot, my sound symbol is covered by a red/white crosss with the message "No audio output device is installed".

In Device Manager, sound is not listed so updating/installing driver there is not an option.

The problem usually corrects itself after a cold boot but now even this is not working!!

Please help.

I'd take that as a sign that the device is failing/has failed...and just try a cheap physical sound card.

<<In Device Manager, sound is not listed so updating/installing driver there is not an option>>

I don't believe that, since Windows will install some defaults whether there is a sound controller installed or not. Sound, video, and Game Controllers should appear in Device Manager. Installing drivers installs the audio controller.

I would ensure that I had attempted to install the correct drivers...before I wrote the audio function off.

Thanks for your reply Louis.

As I mentioned previously, "Sound, video, and Game Controllers" is definately not listed in Device Manager.
If there was or is a way of displaying a screenprint in this forum for further verification, I would do so.

I should add that "Sound etc" is not listed in Device Manager only on the occasions when I reboot and have no sound.
