[alsa-devel] No sound for HP Pavilion DV4z

[aeleneski at comcast.net]

Ok, seems like I have no luck. Here were some general tests that I did and the dmesg results: 

alias snd-card-0 snd-hda-intel

Now something weird is that when I initially changed to just model=hp-dv5, the mute light on my laptop 
went from orange to white. But no sound played. Then after the above tests failed, I started to try different models again (such as auto, laptop) and 
now that light is orange. So I changed back to just model=hp-dv5, and the light is still orange. 

Any other suggestions?

Try model=hp-dv5 with the very latest alsa-driver snapshot below 
ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz 

If you have a luck, it may work. Some HP dv4 model seems to have a 
broken BIOS while some has a correct one.
