I have an HP Envy 17t-3200 laptop.  It has Beats Audio, which includes 2 speakers that sound like tweeter/mid-range speakers and 1 subwoofer for bass.  I get audio working with VoodooHDA version 2.74 and have added my Device ID and Vendor ID to the info.plist.  It gives me speaker output, headphone output and 3 HDMI audio outputs.  The audio from the headphones sounds very good, but the external speaker output does not make the subwoofer work so the external speakers sound very thin and reedy and there is no bass at all.  Any ideas how I can get the subwoofer to work?

have you tried MIDI-setup ?

Nice idea to try Midi-setup.  Unfortunately, only two speakers show up and my only option is stereo.  I guess that says that the subwoofer is not mapped in voodooHDA.  Next step, can that be done manually or through some other means?

OK, after about 3 days of learning and experimenting, I have full HP Beats Audio, including the subwoofer.  It sounds AMAZING!  Here's what I did:

1. I started out with VoodooHDA 2.8.1.
2. I determined that for my laptop, HP Envy 17t-3200, the NID for the tweeters is 13 and the NID for the subwoofer is 16.  I didn't need any patch for the tweeters but I had to add a node patch to the info.plist for the VoodooHDA.kext.  The code I added, immediately below "Nodes to Patch" was as follow:

<array>
<dict>
	 <key>Codec</key>
	 <integer>0</integer>
	 <key>Config</key>
	 <string>0x92170150</string>
	 <key>Node</key>
	 <integer>16</integer>
</dict>
</array>

After saving the info.plist, I installed the kext using kext wizard.  I then rebooted using -f.
3. After rebooting, I went into system preferences and found two Analog Speaker devices.  If you don't find two devices, your subwoofer may be located on a different node other than 16.
4. I then opened Audio Midi Setup and created a multi-output device.  I adjusted the volume of the subwoofer to be about 60% of the volume of the tweeters so that there would be good balance between highs and lows.  I then right-clicked on the multi-output device and selected that it be used for all purposes.
5. One side-effect of this, however, was that I lost all output controls using the multi-output device.  I found a third-party free app, called PTH Volume, and this provides me with audio controls, including hotkeys to allow me to adjust the audio using keystrokes.

I would love to discover an alternative to using a multi-output device and third-party app to control the volume.  However, until I figure that out, this works quite well and, like I said, the sound really rocks.  I hope someone else can benefit from all the work I did to make this work.

I encountered a problem and could use some suggestions:  The way my sound is set up, the speakers (analog) are my two front speakers (tweeters) and I created a second speaker (multi) which is my subwoofer.  When I plug in headphones, the speakers (analog) are disabled but the speakers (multi) are not so I have sound coming out the subwoofer when I plug in my headphones.  For now, I have to manually turn the volume on the subwoofer to 0 and I still get full volume in the headphones,which have a different volume control.  Is there any way to have both speakers disabled when I plug in my headphones?  What kind of code would I need to add to my Info.plist to get that to work?
