Welcome to The Scripts. It sounds like you have two problems, one with your floppy disk, and one with your sound card. I would suggest ripping your floppy drive out of the machine all together; 3.5" drives are almost entirely antiquated these days.
Then you should get online and do a Google search for your sound card, or visit the vendor's website if it is available. Download and install your sound card drivers and then let us know if there are any more problems.
