You only need this if you can't control volume (slider changes but volume doesn't) with VoodooHDA.

 

This fixes the internal volume control via a lame method

 

Instructions :

1 . Remove your current VoodooHDA.kext

2 . Install this one

 

This fix basically relinks volume control from Speaker to PCM

 

Version 2 :

Mute now works

 

10.6.X Compatible :mellow:

 

32 Bit Version:

Mediafire:

64x Bit Version :

Coming soon ...

If you have any problems , reply

Just tried it. It does now allow the volume to change, however I managed to do this before by just changing the Output under the System Preferences.

 

The annoying part is that the Mute button still doesn't work for me. Any chance there is a quick fix for it as well?

function which changes the volume :

 

void VoodooHDADevice::gmixerSetDefaults(PcmDevice *pcmDevice, UInt16 newVolInt)

{

 

logMsg("gmixer setting defaults");

for (int n = 0; n < SOUND_MIXER_NRDEVICES; n++){

audioCtlOssMixerSet(pcmDevice, n, newVolInt, newVolInt);

logMsg("Control integer::%p\n",n);

}

//if (audioCtlOssMixerSetRecSrc(pcmDevice, SOUND_MASK_MIC) == 0)

//errorMsg("warning: couldn't set recording source to microphone\n");

}

 

volume change handler :

 

IOReturn VoodooHDAEngine::volumeChanged(IOAudioControl *volumeControl, SInt32 oldValue, SInt32 newValue)

{

 

IOLog("VoodooHDAEngine0.1[%p]::volumeChanged(%p, %ld, %ld)\n", this, volumeControl, oldValue, newValue);

 

int ossDev = ( getEngineDirection() == kIOAudioStreamDirectionOutput) ? SOUND_MIXER_VOLUME:

SOUND_MIXER_MIC;

 

PcmDevice *pcmDevice = mChannel->pcmDevice;

 

 

mDevice->gmixerSetDefaults(pcmDevice,newValue);

 

return kIOReturnSuccess;

}
