Classic sound issue

WOW Classic mysteriously developed a sound issue within the last week. All game sounds are extremely muffled where they are barely able to be heard. This is the case through both headphones and also speakers. It also appears to only be related to WOW Classic. WOW Retail sounds amazing at full volume, as do other Apps (YouTube, etc). I have a Razer Kraken Tournament Edition (USB) headset, although, once again, it does not appear this is any way related to those, since my desktop speakers also have the same issue. Any help or suggestions?

same here someone help please

Hey there! I tried to see if we could replicate the problem on our end and the sound is coming out pretty clear for me. Does this only happening in specific areas or tasks/abilities?

Could you both provide a DxDiag file to check out? Copy and paste the text file created and paste it between two ~~~ like so:
