[Sound] SiS 7012 problem with IRQ

I just got a new laptop with SiS 7012 integrated audio.  

I put on RedHat 7.3 with stock kernel 2.4.18-3, but the sound device is not
working.  sndconfig was not able to correct the problem.  

I read through some web pages, and the general info is that i810_audio
driver should work with SiS 7012.  However, when I check kernel messages,
it shows a problem with IRQ:  

kernel: Intel 810 + AC97 Audio, version 0.21, 07:42:52 Apr 18 2002
kernel: PCI: Enabling device 00:02.7 (0000 -> 0001)
kernel: PCI: No IRQ known for interrupt pin C of device 00:02.7. Please try
using pci=biosirq.
kernel: i810: SiS 7012 found at IO 0x1800 and 0x1c00, IRQ 0
kernel: i810_audio: unable to allocate irq 0

I have tried using the boot parameter  pci=biosirq  but no effect, same

Any one has an idea how to resolve this?
