You may be out of luck with your sound card but we will
offer a few ideas. The sound card they put in those machines weren't
the best and can be very trick to get working with Windows 95. First
try all the drivers from Packard Bell on your PC that you think might be
for that card. I think the Aztech chipset was popular in those
PC. Be careful though, their drivers have a reputation for causing
Windows 95 to crash or misbehave.
In fact, if you haven't already tried them all, wait and
do this first. Set up your new sound card in Windows 95 as a
Creative Sound Blaster or Compatible. This will probably be
your safest shot compared to messing with those drivers from Packard
Bell. You will probably have to try different settings for the
device until you get it to work. You probably wont get loud sound
out of the card so you will need to get some speakers with an amplifier.
Beyond this, the only thing left is to load the drivers in
DOS before Windows 95 starts and try to get Windows to recognize it.
