it appears you don't get any sound because the outputs are controlled
by gpio pins.  see if the following fixes it.

1. save this mail as a plain text file somewhere.
2. make sure you have kernel sources installed.  (see the faq if necessary)
3. cd /sys/dev/pci && patch -p 0 < <path to this file>
4. build and install kernel. (see faq if necessary)
5. reboot
