Interruption conflict causes the sound card to be unusable

[Sound Card Faults] Views: 309
 
When the system starts, the sound is normal, but as long as the music file is played, it will freeze, and it will not work after checking and killing the virus. Check in the "Device Manager" and find that all devices are displayed normally. Later, open "System Information" → "Components" → "Problem Devices", the device: ACPI IRQ Holder for PCI IRQ steering, PNP device ID: ACPI\*PNPOCOF\ 00000002, error code: 22 appears in the right column. After testing, it seems that there is a conflict in the equipment, but it cannot be corrected.
From the description of the fault phenomenon, this situation should have nothing to do with the virus. The virus will not only infect the driver of one device without affecting other files. The main reason for this situation is that the equipment cannot be used normally due to interruption conflicts. Sometimes when the interruption of the system equipment conflicts, no problem can be seen from the surface of the operating system, but the equipment cannot be used normally at this time. In judging this type of situation, a certain amount of experience is required.

To solve the interruption conflict problem, you can uninstall the sound card driver first, replace the PCI slot of the sound card, and then reinstall the driver, the fault can be resolved.
