I had added before pin configs for which source came from *.ini files of IDT
windows drivers provided by HP. But I don't know if they are at all necessary,
may be just setting config of 0x0d pin should suffice for all hp-dv5 models,
as all of them have speaker on 0x0d from all reports and also looking at the
*.ini files.

I have three patches, you can choose one of them :), see attached. The first
one is my previous pin configs work "let's set for all cases the pin configs
based on *.ini files", the others are same smaller change/less intrusive that
instead just deals with this hp dv4 case.
