Thinkpad T42p sound stopped working.

[Understudy]

Hi,

I recently had my sound stop working. It was fine and today it decided 
to just stop. I threw in my old hard drive and sound worked fine on that.

So lets go over what I have here.
Thinkpad T42p
FreeBSD Gargoyle.brendhanhorne.com 7.2-RELEASE FreeBSD 7.2-RELEASE #0: 
Tue Aug 11 08:51:16 EDT 2009     
root at Gargoyle.brendhanhorne.com:/usr/obj/usr/src/sys/STONE  i386

Gargoyle# cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2007061600/i386)

Gargoyle# ll /dev/dsp*

In my kernel

dmesg

Gargoyle# cat .history > /dev/dsp
produces no static sound at all.


So what I can I do now?

Sincerely,
Brendhan
