Re: [Fwd: HP DV4 1155 SE - No Sound through, speakers...]

[Guy Stalnaker <jstalnak@wisc.edu>]

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.

BEST regards,

Guy S.
