Inspiron 1525 snd_hda problem

[Pete Rushmere]

Hi all,

Running FreeBSD 7.0-RELEASE on a Dell Inspiron 1525, there is a problem with 
the sound though - snd_hda loads fine but I get nothing from the speakers or 
headphone jack. Overall the laptop isn't bad, X runs nicely, wifi is up and 
running but to be truly useful I need the sound too ;-)

For the record, snd_hda runs perfectly on my 7.0-RC1 desktop box, however that 
is an nvidia chipset...

I have googled this to death and got nowhere at all. Here's some debug output, 
can anyone help with this?

Thanks,
Pete.
