Herton and Takashi, I can confirm that compiling and installing the latest snapshot of alsa-drivers, adding "model=hp-dv5" to /etc/modprobe.d/alsa-base, and running hda-verb with the parameters Takashi indicates DOES result in sound from the onboard, internal speakers on my Hewlitt Packard dv4 1225 Pavilion Entertainment PC. The mute on headphone use does not work, but that's okay by me for now. I think you're on the right track in diagnosing the problem and it's solution. Thank you very, very much for helping us. I know it'll likely be a while before the solution actually makes it into distributions, but at the least I can use my sound apps without having to plug my laptop into something to hear what's playing. Kinda defeats the notion of having a laptop if one has to keep it plugged in. Do either of you mind if I collate notes from the posts exchanged on alsa-devel and post them on the Ubuntu forums? There are a lot of other HP users who have posted about the same problem. It's likely they have no idea the resource available to them in the alsa-devel archives.
