In some cases you may need to mute Monitor instead of iGain.Problem: audio delay. If you change volume, for example, it takes 1 or 2 seconds to play the test sound.Solution 1: delete com.apple.audio.DeviceSettings.plist and com.apple.audio.SystemSettings.plist from /Library/Preferences/Audio and reboot.Solution 2: use .Problem: inputs or outputs don't show in sound preferences.Solution 1: look for a kext patched for your codec.For VT1708SFor AD1988BSolution 2: add NodesToPatch basead on getDump output (download in official thread).Example<key>NodesToPatch</key>

style='color: #71f01CAd (Codec Adress) NID (NodeID) Verb Command Verb Data71cXY X=Default Association Y=SequenceDefault Association and Sequence are used together by software to group Pin Complexes (and therefore jacks) together into functional blocks to support multichannel operation.
Software may assume that all jacks with the same association number are intended to be grouped together, for instance to provide six channel analog output.
The Default Association can also be used by software to prioritize resource allocation in constrained situations.
Lower Default Association values would be higher in priority for resources such as processing nodes or Input and Output Converters.
Note that this is the default association only, and software can override this value if required, in particular if the user provides additional information about the particular system configuration.
A value of 0000b is reserved and should not be used.
Software may interpret this value to indicate that the Pin Configuration data has not been properly initialized.
A value of 1111b is a special value indicating that the Association has the lowest priority.
Multiple different Pin Complexes may share this value, and each is intended to be exposed as independent devices.Sequence indicates the order of the jacks in the association group.
The lowest numbered jack in the association group should be assigned the lowest numbered channels in the stream, etc.
The numbers need not be sequential within the group, only the order matters.
Sequence numbers within a set of Default Associations must be unique.*My notes for this, if you look on the vanilla codec verb(no matter what codec) you will see that Sequence is always 0.Why that, and why for us on our codec verbs is different? Simple b/c Apple dosen't have multichannel analog out! so you must change it to 0.*About Default Association, Keep the default one, in order, and on those that are the same replace them with new one that dosen't exist already in the dump... the values you can use are: 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d and f.(see what does verbit if you still don't understand)71dXY X=Color Y=MiscColor indicates the color of the physical jack for use by software.Unknown 0
Reserved A-D
Other FMisc is a bit field used to indicate other information about the jack.
Currently, only bit 0 is defined.
If bit 0 is set, it indicates that the jack has no presence detect capability, so even if a Pin Complex indicates that the codec hardware supports the presence detect functionality on the jack, the external circuitry is not capable of supporting the functionality.Reserved 3 Reserved 2 Reserved 1 Jack Detect Override 0 *Use 0 for Jack Detect - External Device(e.g. Headphones Mic etc) Use 1 for Jack Detect Disabled - Internal Device(e.g. Internal speakers, Internal mic)71eXY X=Default Device Y=Connection TypeDefault Device indicates the intended use of the jack or device.
This can indicate either the label on the jack or the device that is hardwired to the port, as with integrated speakers and the like.Line Out 0

Software can use this value to know what Pin Complexes are connected to jacks, internal devices, or not connected at all.00b - The Port Complex is connected to a jack (1/8&, ATAPI, etc.). 01b - No physical connection for Port. 10b - A fixed function device (integrated speaker, integrated mic, etc.) is attached. 11b - Both a jack and an internal device are attached.
The Information provided in all other fields refers to the integrated device.
The PD pin will reflect th the user will need to be queried to figure out what it is.Location indicates the physical location of the jack or device to which the pin complex is connected.
This allows software to indicate, for instance, that the device is the “Front Panel Headphone Jack” as opposed to rear panel connections.*Details:Convert the 2 digit hex number to binary.Pad the front with zero's to make it 8 dgits. Example:0x02 = binary 10 =

Thanks so much for this! I'll try some of these.
BTW, some of the lingo probably passed over my head, but do you know how to get surround sound working?
Usually (at least in the codecs I tested) all line-out have the same default association, only the sequence changes. You have to set a different default association for each line-out and set sequence as zero.Once you have 3 or 4 line-out working, create an aggregate device, configure the speakers and select it in sound output.Check this example*About Default Association, Keep the default one, in order, and on those that are the same replace them with new one that dosen't exist already in the dump... the values you can use are: 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d and f.(see what does verbit if you still don't understand)
Thanks Crosx86
Thanks to this guide the audio works, but not perfectly. I hear a little background noise (like crackling noises).

Magically the audio doesn't work anymore.
@buoothe problem in this edition of the nodes, I think.simple patch your dsdt and install the voodooHDA 2.7.2.pkg and edit the info.plist of the kext:<key>IOMatchCategory</key>
<string>VoodooHDADevice</string>
<key>IOPCIPrimaryMatch</key>
<string>0x27d88086</string>
<key>IOProviderClass</key>
<string>IOPCIDevice</string>you're right the sound still works perfectly, more now.works best.with codec dump I did not succeed, controls lit up, but without sound.
You have to specify the Codec key in each node patch.Where did you get the &default& NodesToPatch?Post your VoodooHDA getDump.About the crackling sound, see here
Thanks guys I'm using voodoohda 2.7.2, I only added my PCI ID.<key>IOPCIPrimaryMatch</key>

Hi man, I don't understand the portuguese but I want to try it xD1 minute...Wow! This is the first VoodooHDA 2.7.2 that doesn't give me noice.But It gives me too much audio delay and the mic doesn't work.Crosx86, do you know how to eliminate the audio delay?

Your get dump is the same as mine?
put your device id and your vendor ID in the plist kext if it is already there, delete all nodes and run vooodoo get dump and compare.
Our chips are different :\
I'was looking your codec_dump, however ...do you know how to eliminate the audio delay?
Edit: It is the same 0x27d88086

Could you take a look here?

</array>You need put it line-out,use this string:0x in node 26
Please see my post aboveYou just need to add in NodesToPatch the nodes you want to patch, the ones that are fine with the default Config you don't need to add.The error is using default association 4 for node 26, it's already used in node 24.
The mic works but I hear it in the speakers and I'm not able to decrease the volume(of the mic).
Problem: audio feedback (Larsen effect), sound loop between input (microphone) and output (speakers).Solution: mute iGain and increase iMix or Mic if microphone doesn't work<pre class='prettyprint lang-&key&iGain&/key&&string&0&/string& _linenums:0'>&key&iGain&/key&&string&0&/string&It can also be done in the prefPane. In some cases you may need to mute Monitor instead of iGain.I'm not able to decrease the volume(of the mic)Try to do it in VoodooHDA prefPane, once you find a good value you can set in Info.plist (MixerValues), but the value set in prefPane will be restored after reboot if you use voodoohdahelper (installed by the pkg).
I found another solution to the delay problem (worked for me): delete com.apple.audio.DeviceSettings.plist and com.apple.audio.SystemSettings.plist from /Library/Preferences/Audio and reboot.
