This probably happened because the audio chip is not supported by the
version of the i810_audio driver in the kernel (kernel driver is too
old).

This happened because insmod does not check module dependencies.  Other
modules must be loaded first.  modprobe takes care of this.

The solution is to update your kernel (which is difficult because Red
Hat systems require NPTL kernels) or to use ALSA drivers (use the driver
snd-intel8x0).

Is this a laptop or a desktop?  If the former, which one?  If the
latter, what motherboard?
