Howdy,

Thanks to a generous FreeBSD user I have a shiny new Dell Optiplex 960, 
with the following device:

hdac0: <Intel 82801JD High Definition Audio Controller> mem 
0xf7adc000-0xf7adffff irq 16 at device 27.0 on pci0
hdac0: HDA Driver Revision: 20100226_0142
hdac0: HDA Codec #0: Analog Devices AD1984A
pcm0: <HDA Analog Devices AD1984A PCM #0 Analog> at cad 0 nid 1 on hdac0
pcm1: <HDA Analog Devices AD1984A PCM #1 Analog> at cad 0 nid 1 on hdac0

There's 2 problems. When I plug the headphones in there are sounds, 
sometimes a low-level sound like a tea kettle whistling, and sometimes a 
louder screeching sound. The other problem is that the front headphone 
jack doesn't work. The rear one works, but this is less than convenient. 
:)  Windows and ubuntu linux do not have either problem with the same 
hardware.
