How to: Resolve a plug-and-play sound card interrupt request (IRQ) conflict.
Solution:
Open the 'Device Manager', and select the sound card driver. Change the IRQ setting for the sound card to an unassigned IRQ value, and restart Windows 95.
1) Open the 'Device Manager', and select the 'View devices by type' radio button.

2) Double-click 'Sound, video and game controllers' in the 'View devices by type' list box.
3) Double-click the sound card driver. (The sound card driver 'Properties' dialog box appears.)

4) Click the 'Resources', tab, and if the 'Use automatic settings' check box is selected, clear it.
5) Select the 'Interrupt Request (IRQ)' resource in the 'Resource settings' list box, and click 'Change Setting...'. (The 'Edit Interrupt Request' dialog box appears).

6) If you do not know which IRQ is causing the conflict, view assigned IRQ values to determine which DMA is involved in the conflict. The IRQ involved in the conflict will have a yellow circle with a black exclamation mark in its center on its icon.
7) Select a new IRQ from the list of available IRQs in the 'Value' drop-down list box and click 'OK'.
NOTE 1: If you have a real mode driver loaded in the AUTOEXEC.BAT for the sound card, you will need to make changes to the real mode driver to reflect the IRQ setting change in step 7). Refer to the sound card user manual for instructions on how to configure a real mode driver for the sound card.
NOTE 2: If the 'No Modifications Allowed' message box appears, this resource cannot be changed. You must change the IRQ setting on the other device that is configured to use this DMA value.
8) Click 'Yes' to restart Windows 95.
