I just installed a 3DForce2 MX-32 AGP 4x video card in my compaq presario pc. It works great and the installation went off without a hitch. Now, however I have NO SOUND! I called the company jaton.com and they said they had never heard of such a thing. I took the card out and rebooted the machine without it and the sound was back. Then I put the card back in and the sound is gone again. Any suggestions PLEASE!!! Thanks!
