[Ambassadors] kernel upgrade breaks sound line-out (speaker port)

[Debjit Saha]

an upgrade to kernel 2.6.27.9-159.fc10.i686 from kernel
2.6.27.7-134.fc10.i686 has rendered the line-out not working for me.
as in when I use the laptop speakers I get sound but when I connect
the speakers to the line-out port I dont get sound!!!
