The problem was that your BIOS didn't set the correct default pin configuration. The driver doesn't know which pin should be used for the speaker output, as a consequence, it's set as INPUT. Now you set it OUTPUT manually by hda-verb, and (fortunately) the route to that pin was alive even though it wasn't declared, you get the speaker output now.
The next step is to implement a proper pin-config to override by the driver. This won't be much work, but hey, wait for a while.
(Or, did Herton already work on that?)
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.
I took the last, the smallest one. It's not too bad to define all models, but at this stage, I'd like rather to slim the code down.
Thanks!
