I, too, have been having the same problem: No sound. When I attempt to configure
any sound settings in Control Panel, I see many greyed out boxes that state "no audio
devices installed", even though the drivers have been installed, and investigations
into device manager claim that "device is working properly".
I know the sound card was working fine at one point, and then it stopped. I know
it's not the sound card, but, to be certain, I took out the creative labs sound card
and installed a Philips sound card, AND IT DID THE SAME THING! I have unistalled
and reinstalled the software countless times. It's as though some other process has
claimed use of the device. Could this be a new form of virus?
Microsoft's troubleshooters seem to bring me back to dead ends, with the most recent
trial complaining about signed drivers. I went to the Philips web site and they told
me to ignore those messages.
I came to this site and have taken the following advice before posting this latest
addendum to my message.
I downloaded and ran Norton's AntiVirus program, which found 8 files corrupted with
the Benjamin virus, that was snuck inside a downloaded copy of Grand Theft Auto.
Norton's AV deleted those files, but the problem persisted. Then I reinstalled the
XP os from cd. The good news is that it did not remove the users, or their settings,
during the process. The bad news is that the problem still persists.
I am beginning to believe that this could be a new form of virus that insinuates
itself in the registry in such a way as to disable the sound card. The most unique
set of symptoms that sets this virus apart from others is that Device Manager reports
that "the device is working properly", and, yet, when I go into Control Panel and
look at the "Sounds and Audio Devices Properties" dialogue box, on the main screen
it states that "No audio Device" is installed, and all other fields on that screen,
and others, is greyed out.
I have again reinstalled XP, installed SP1, downloaded latest patches, with no results.
Noto bene: This is not a hardware problem! As others have done, I have replaced the
sound card entirely with a brand new sound card, with new drivers, but with no success.
The problems seem to start after a virus has attacked the system and, even after
the successful removal of the virus, the audio devices no longer work. As you read
these posts, also note the similarities of many of these problems that others are
reporting. Coincidence? I think not. I am still stymied, though, and would welcome
any help in this regard.
Please feel free to e-mail me at jmangione@knowledgewave.com, as well as post a reply,
if you think you know what's wrong.
