http://www.projectosx.com/forum/index.php?showtopic=355How to edit Info.plist:
viewtopic.php?f=18&t=1704Problem: kernel panic.
Solution 1: remove AppleHDA and restart the system before installing VoodooHDA (or use AppleHDADisabler).
Solution 2: edit Info.plist, replace the key
IOPCIClassMatch by
IOPCIPrimaryMatch and put the PCI ID of your audio card in string.
Before
Code:
<key>IOPCIClassMatch</key>
<string>0x04030000&0xffff0000</string>
After
Code:
<key>IOPCIPrimaryMatch</key>
<string>0x3b568086</string>

viewtopic.php?f=18&t=63Problem: kext doesn't work (usually when there's more than one audio card or the video card has HDMI audio).
Solution: use solution 2 for kernel panic problem above. If you want to use both cards, create one entry for each card in IOKitPersonalities.
Problem: sound crackles.
Solution 1: change output format in
Applications - Utilities - Audio MIDI Setup
Solution 2: check "Use SSE2" in VoodooHDA prefPane
You can also enable
Vectorize in Info.plist
Code:
<key>Vectorize</key>
<true/>
Problem: volume control (slider) doesn't work.
Solution: enable
VoodooHDAEnableVolumeChangeFix in Info.plist
Code:
<key>VoodooHDAEnableVolumeChangeFix</key>
<true/>
Problem: volume too low.
Solution: enable
VoodooHDAEnableHalfVolumeFix in Info.plist
Code:
<key>VoodooHDAEnableHalfVolumeFix</key>
<true/>
Problem: audio feedback (Larsen effect), sound loop between input (microphone) and output (speakers).
Solution: mute
iGain and increase
iMix or
Mic if microphone dosn't work
Code:
<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.
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
SoundFlower.
Problem: inputs or outputs don't show in sound preferences.
Solution 1: look for a kext patched for your codec.

http://www.insanelymac.com/forum/index. ... pic=267898Solution 2: add
NodesToPatch basead on
getDump output (download in official thread).
Example
Code:
<key>NodesToPatch</key>
<array>
<dict>
<key>Codec</key>
<integer>2</integer>
<key>Config</key>
<string>0x90a70120</string>
<key>Node</key>
<integer>12</integer>
</dict>
</array>
Config (PinDefault) is made up of the last 2 digits of each codec verb, but in the opposite order
Code:
0x01014410 = 21471c10 21471d44 21471e01 21471f01

More detailed exampleviewtopic.php?f=18&t=604Info about codec verbsSource:
http://www.projectosx.com/forum/index.php?showtopic=465For each input/output there is a sequence of 4 verbs.
Code:
Jack Color Description Node PinDefault Original Verbs
--------------------------------------------------------------------------------------------------------
1/8 Green Line Out at Ext Rear 20 0x14 0x01014410 21471c10 21471d44 21471e01 21471f01
Its about NodeID(NID) 0x14 in hex, 20 in decimal.
The default verbs for it:
21471c10 21471d44 21471e01 21471f01CAd (Codec Adress) NID (NodeID) Verb Command Verb Data71cXY X=Default Association
Y=Sequence
Default 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=Misc
Color indicates the color of the physical jack for use by software.
Code:
Unknown 0
Black 1
Grey 2
Blue 3
Green 4
Red 5
Orange 6
Yellow 7
Purple 8
Pink 9
Reserved A-D
White E
Other F
Misc 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 Type
Default 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.
Code:
Line Out 0
Speaker 1
HP Out 2
CD 3

AUX 9
Mic In A
Telephony B
SPDIF In C
Digital Other In D
Reserved E
Other F
Connection Type indicates the type of physical connection, such as a 1/8-inch stereo jack or an optical digital connector, etc. Software can use this information to provide helpful user interface descriptions to the user or to modify reported codec capabilities based on the capabilities of the physical transport external to the codec.
Code:

71fXY X=Port Connectivity
Y=Location
Port Connectivity indicates the external connectivity of the Pin Complex. 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 the status of the jack; 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:
Code:
0x02 = binary 10 = 00000010 8 digit binary
