Hi, I have an Intel HDA card, Conexant CX20551 (Waikiki) model, Subsystem Id: 0x103c30b2 (HP DV2000 series).
With these settings, there are 4 volume controls: "PCM-2" and "Speaker" to control speakers, "PCM" and "Headphone" to control headphones. At the moment "PCM-2", "Speaker", "PCM" work fine, but "Headphone" has no effect (also reported inside bug #3091).
With the following patch, the "Headphone" volume/switch work as intended, with no effect on other functionalities.

Also, there is no "Master" control to set the volume for both speakers and headphones. The patch below adds a master volume (and a master switch) that work ok for me. By the way, with the patch the light on the mute button changes between blue and red, which is a nice plus.

I am no expert of Conexant hardware and I don't know if those changes are correct for all the devices that share the same code (the 103c:30xx), but I'm confident that they are the right ones for the 103c:30b2 device.
Can someone take a look? Thanks.
