I haven't used 98 for a while, but if you go into device manager and view hardware 'by connection', you should see the shared I/Os listed. Click on the soundcard & see if you have a choice of other IRQs. If not you need to see if the soundcard has any jumpers for selecting the IRQ manually. If still no joy you need to access the BIOS and look for the section on 'legacy devices' where you will need to mess around with trying different settings for the card (it's what we used to have to do in the days before 'plug'n'pray').
