herton or Takashi,
How does one go about applying a patch like the ones attached to Message 6? And to which files are they applied? I assume they are meant for the alsa-driver code, but that's as much as I know (well, I know how to run ./configure, make, and make sudo :). I'd very much like to see if the patches work for my HP dv4 1225.
Regards,
Guy

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.
thanks,
Takashi

Did you try the latest alsa-driver snapshot? If it still doesn't work, I guess this is a BIOS problem. The other HP dv laptops show the widget 0x0d as the speaker while yours is unused. Try to run: hda-verb /dev/snd/hwC0D0 0x0d SET_PIN_WID 0x40 Takashi-- []'s Herton
