Basically there were two lines of code in the driver pkg which restricts installing the driver to OSs newer than 10.8 . I changed those lines. Now you can get stereo sound in and out from your computer just with an usb cable.

I've struggled so much to run this on BigSur but driver makes changes on system volume and I didn't know what to do so If someone else can make some more edits it can be installed in BigSur too but be careful because BigSur really is something else.

I've installed this on an OS X El capitan (I accidentally set my computer back to factory settings while trying to downgrade from BigSur to Catalina) then upgraded to Catalina. Didn't need to reinstall it.

If anybody downloads this to Catalina and then upgrades to BigSur I'd really love to see their feedback because I don't know if it works on BigSur.

Here's the link for the modified pkg : https://yadi.sk/d/jr8rHEnMXfnEdw

Here's how you can install drivers on Catalina: https://www.youtube.com/watch?v=l-LvtuUxAQc

When I installed it on El Capitan last step was not needed but Apple's making it harder to modify that volume and on BigSur it's impossible.

Hi! I just commented in this forum about this :) I used your installer but it didn't let me go further because of Big Sur incompatibility. That is why I tried to install everything manually.
