How to uninstall Corel Painter Internal Audio Driver in OS X Yosemite

https://apple.stackexchange.com/a/223799/383276 the link here is the same answer given by Hamid...Its perfectly working so just use the commands given in the answer.

I found a post about uninstallation of this audio driver. There is a kernel extension named PainterAudioDriver.kext in /System/Library/Extensions/ that adds the audio driver to the kernel space. To ensure that the kernel extension is loaded I used kextstat:

kextstat | grep corel

The result was:

  131    0 0xffffff7f80fde000 0x4000     0x4000     com.corel.painter.PainterAudioDriver (1) <96 5 4 3>

Then to unload the kernel extension I used kextunload that is explained here:

sudo kextunload -b com.corel.painter.PainterAudioDriver

After that the Internal Audio Driver (Corel Painter) is removed from both Sound menu bar and Audio MIDI Setup. To prevent the driver from loading again while rebooting the system, the kernel extension file must be removed from /System/Library/Extensions/ with this command:

sudo rm -r /System/Library/Extensions/PainterAudioDriver.kext

The Corel Painter Internal Audio Driver is uninstalled now.

I suspect Corel has for some reason set itself up as either an Aggregate or Multi-output device in AudioMIDI

Applications > Utilities > Audio MIDI Setup
Cmd ⌘ 1 to show Audio devices if it doesn't show automatically.

If my suspicion is correct, you will see one of the 2 circled icons, named after Corel.

Select, then click the - sign underneath to remove.

This won't 'break' anything. These device types are user-created & deleted. It will not allow you to delete any real device.

Boom2 may also have set itself up in a similar way, so make sure to get the correct one, if you wish Boom2 to continue working correctly.

BTW, it is highly unlikely to have an actual associated driver installed, it is merely a way of 'patching' outputs for convenience, all done using Apple's own routing capabilities.

It's probably in one of the subfolders of /Library/Audio/ but then I do not have any custom audio drivers installed... so I can not confirm that!

If you still have the Corel Painter .pkg file you can open it as if you were going to reinstall it and look for a menu option "Show Files" that will shows you a complete list of every single file it would install. You can then scan through and look for /Library references to get an exact answer.
