mergesoft Posted February 27, 2016 Share Posted February 27, 2016 I can't adjust my volume on my Dell Latitude E6520. It just stays at max. What can I do? I'm running OS X El Capitan. I'm using Clover. I have the NVIDIA 4200m/i7 Model. I have attached my EFI folder. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted February 27, 2016 Moderators Share Posted February 27, 2016 You can either use the DSDT plus E6420 bootpack here which includes the patched version of AppleHDA or you can modify the info.plist of VoodooHDA. Look for these under IOKitPersonalities and change it to true VoodooHDAEnableHalfMicVolumeFix VoodooHDAEnableHalfVolumeFix VoodooHDAEnableVolumeChangeFix VoodooHDAEnableMuteFix Link to comment Share on other sites More sharing options...
