On my Precision M4800, I'm working on getting audio working somewhat better. Here is the situation where I am now:
I patched the DSDT to let AppleHDA work with HDMI sound -- it works perfectly.
The internal speakers and headphone ports are being handled by VoodooHDA. The speakers work. The internal microphone works. I don't have an external microphone to test.
There is also a headphone/speaker jack on the docking station for this laptop. It also works.
In the audio settings, I get Speaker (Analog) and Line-out (Green Rear). Both of these work. The Line-out green rear is referring to the docking station line out port.
When I plug in earphones, Speaker(Analog) changes to Headphones (Green Front). However, no sound comes out of the headphones. I can't find the headphones in the voodoohda preference pane.
Any idea of what I can do to enable the headphones? The audio chipset is Realtek ALC3226, which may be the same as ALC292.
In case it matters, in my DSDT, I have an HDEF device that looks like this:
