As a result, I took it upon myself to pester the powers that be to undo this change on my personal client, and I see others looking for this solution as well. I will outline the steps to revert the audio changes, what to do in case this causes other problems, and disclaimers to using this entire process below.
DISCLAIMER: Neither I nor Turtle staff accept any responsibility for problems that arise from tampering with your WoW.exe binary. If you are not familiar with hex editing, you SHOULD NOT use this guide. Please follow the steps exactly and do not change anything other than what is listed.
Before making any changes, it is advised that you make a copy of your WoW.exe and name it something you'll recognize, like WoWbackup.exe or WoW.exe.backup or anything you desire. You can skip the following process if you already know what to do from this image shown:

In order to apply this fix, you are going to need a hex editor of your choice. Personally, I prefer TinyHexer. You will want to open this program and drop your WoW.exe in, and you should see the binary of the program as shown below.

Referencing the image shown with the offsets and addresses, you are going to want to navigate to those specific offsets and change those bytes AND THOSE BYTES ONLY. You can do this through Ctrl + G to open a prompt where you must type the exact offset shown.

This will take you to the exact byte you want to edit. BE SURE THAT YOU ARE IN INSERT MODE (hit the Insert Key). This will be indicated by your cursor being a flashing box rather than a flashing line.

Type the byte values listed above for the specific offsets. Therefore, we are changing 385D to 9C5C. If you did this properly, none of the bytes to the right of where you are editing should have shifted, and your new byte values should be highlighted in yellow. If this is not true, use Ctrl + Z to undo any change you just made.

Repeat the process of Goto Offset (Ctrl + G), using Insert Mode, and changing the byte values for all 3 listed offsets. Once you are done save the file in your hex editor and close. In the case of Tiny Hexer, a backup of your pre-edited file will be saved automatically in the same directory so that if you break something, you have a fallback.
And there you have it. You now have the same sound configuration as the previous client had.
