snd_hda and play interrupt

[kpitcher at keithpitcher.com]

I have a HP Pavilion dv6258se. With 6.2-Stable, I applied the diffs and
made the kernel modules.

Things load just fine, however no audio plays and I get an error message 
anytime I try to send audio through.

from dmesg :
pcm0: <NVidia MCP51 High Definition Audio Controller> mem
0xb0000000-0xb0003fff irq 11 at device 16.1 on pci0
pcm0: <HDA Codec: Conexant Venice>
pcm0: <HDA Driver Revision: 20061017_0033>
pcm0:play:0:dsp0.0: play interrupt timeout, channel dead

This repeats every audio request.
pcm0:play:0:dsp0.0: play interrupt timeout, channel dead

> tail /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <NVidia MCP51 High Definition Audio Controller> at memory 0xb0000000
irq 11 kld snd_hda [20061017_0033] (1p/1r/0v channels duplex default)

My pciconf is :
pcm0 at pci0:16:1: class=0x040300 card=0x30b7103c chip=0x026c10de rev=0xa2
hdr=0x00
    vendor     = 'NVIDIA Corporation'
    class      = multimedia

Digging through the archives, I saw a mention of bios settings. However,
this bios has no IRQ settings in it. Can't change much of anything in the
bios.

Any suggestions would be helpful,
