Hi, I am running XP SP 2 on Intel Motherboard DH55TC, Core i5 CPU. UAA High Definition Audio class driver is resulting in high hardware interrupts that uses upto 10 to 12% of CPU. The interrupts goes away if I uninstall UAA Bus driver through Device Manager. But this also disables RealTek audio driver which means I hear sound no more. I tried updating the UAA driver to Version 1.0a but still the hardware interrupts wont go away. Please help how to fix this issue.
