audio on HP Pavillion DV4z

Yes, I also have this problem. Sound through headphone jacks, but not through speakers. The only difference is I am using Kubuntu.

Hello, I'm a noob. Just got done installing Hardy on DV4-1222nr pretty much same as DV4-220us (previous post). My sound works fine during initial installation. Upon updating system, sounds stop working on Laptop itself. At home I have a HP Docking station and while the laptop is docked, sound works beautifully. I'm fairly certain that the sounds are coming through the headphone jacks (when not docked) but I haven't validated that either.

I just upgraded to Intrepid and now the sound isn't coming out of the Dock (XB3000) nor the laptops internal speakers. I DID manage to plug in a set of headphones and the sound IS coming through the headphones. Still searching for a solution, just thought I'd post my findings.

Folks,

The solution is given in

Basically its fixed in the newest version of alsa but since it will take a few weeks/months for ubuntu to move to that version you will need to install it yourself.

If you are comfortable with doing things in the command line and more importantly keeping track of what you did so that you can repeat it after a kernel upgrade, go ahead as given in the thread above. I have it working on my dv4 perfectly.
