Hiya.

I've just re-installed WinXP for a friend who was having plenty of
problems (too much spyware and too many viruses to even bother to try
to fix, just wiped and re-installed from scratch) and now I can't get
the audio to work.

The audio card is an nVidia one. The clean install was from their
WinXP SP1a CD so I downloaded SP2 and installed it, then downloaded
about 90 updates from Windows Update which included three updates for
the nVidia audio card and rebooted. Upon installing the updates the
PC bleeper stopped beeping on errors/warnings/etc as if it was binging
from the audio card but no sound is forthcoming.

I rebooted and played an MP3 from within WinAmp and no errors were
returned and the GEQ was bouncing away merrily as if music was playing
but I got nothing from the speakers. I double clicked the speaker
button on the task bar next to the clock and went to Advanced and
checked all the boxes to display all the various feeds, unmuted them
all and set the volume to max on them all but still nothing.

I then unplugged the amp from one socket on the sound card and put it
in the other (there are only two, and a what looks like an optical
digital output) which I assume was the Mic/Line In socket and repeated
everything but still no joy.

I swapped the plugs over again and tried the same in Windows Media
Player, same result.

I then went to nVidia's website and downloaded the latest drivers from
there, installed them (tapping 'continue' on the non-Windows Logo
Compliant boxes) to see if that did anything but after a reboot still
nothing. Infact, WinAmp crashes on the drivers from nVidia's
website. I soldiered on and went to the nVidia audio control panel
with the music playing in Windows Media Player and all of the stuff
from the nVidia GEQ is pumping away as one would expect, but there's
just nothing coming out of it.

I unplugged the amp completely and stuck some working earphones in it
for a second opinion (in both sockets at the back) but no audio was
coming out of them so swapped back to the amp.

I then fiddled with the 'rear is plugged into line in socket' style
entries in the volume controls area but that didn't do anything
either.

I then hit the 'mute' option in the normal audio control next to the
clock and there was a click from the amp. Unmute, click. Mute,
click... that seems to imply to me that the sound card is responding
to the software as the mute button is of course software driven. Upon
checking to make sure everything was being displayed and unmuted and
at full volume I have no idea at all why I don't get any audio out of
the sound card even when it all looks like it's working.

None of the devices are highlighted in device manager and are marked
as working properly. Running dxdiag.exe reports that the card is
working and the audio tests work but without output to the tests. I
tried turning the audio accelleration to none and retesting but still
nothing.

Any ideas?!

I would not rely on the Microsoft Updates for Hardware Drivers. Go to
Nvidia's website and download the audio and
nvidia chipset drivers.
