Windows AUDIODG.EXE crash due to THXSYSVAD2APO.dll

I'd try reinstalling THX driver, or try to repair system by running cmd as an administrator then typing: sfc /scannow
You can also try to update your W10 to 20H2 version. Seen many times, that some function/app was not working until windows was updated to higher version.

Was there ever a confirmed resolution on this? I am having the identical problem with a new Razer Blackshark V2 Pro. It is crashing my enter system over and over:

The issue is with the THXSYSVAD2APO.dll that is part of the Virtual THX Spatial Audio device itself and Razer needs to update it.

I have this exact same error if I leave the THX Spatial Audio set as the Default Sound Device with the Razer BlackShark V2 Pro set as the Default Communication Device which is the recommended default from the Synapse 3 software. If I set the default device in Sound Properties to JUST the BlackShark V2 Pro only this error does not occur whatsoever.

I have updated the BlackShark V2 Pro to the latest firmware, I have removed and re-installed the Synapse 3 Software, I've changed USB ports that the wireless receiver is plugged into and I even went as far as completely wiping the entire OS from the system and reinstalling Windows from scratch from a Windows Installation USB Drive and the error still persists when the THX Spatial Audio is set as the default device.

My system is fully up to date with all the latest available drivers and bios, and my full specs are below.

I tried opening a ticket about this issue too, but Razer's support staff was useless. It would be nice to get some kind of answer regarding this issue. Even a we're looking into it would be nice.

Hello anyone from Razer!? This is still an issue despite the recent updates to Synapse, it's been an issue since January / February and it's now April. An acknowledgement of the issue would at least be nice, a fix would be even better.

Same error, same issue as well. Sadly, even when i change it from THX to some other playback device the error still persists. Everything up to date. It's beyond me how Razer thinks this will not affect their reputation. Every game is crashing due to this for me.

Great to hear people are experiencing the same problem, of course it is not good news. I guess I'll go ahead and follow your advice first and see if it works before I reinstall my OS. I've tried the other tricks you've mentioned @Flexo_3370318.

I just want to add my name to the list of people with this same problem. Tried updating firmware, clean reinstall of windows, clean install of synapse, running it as admin, sfc, etc. Synapse will open for a couple of seconds, but will then simply crash without posting an error (its logged in event viewer). I have even tried not installing the blackshark v2 and only install my Basilisk Ultimate mouse in the hopes that i can set a macro for the paddle button so that i can actually use the damned thing in a game.

Total waste of money. I can't believe there isn't a way to map the mouse buttons via a third party app. NO I CANT RUN SYNAPSE LONG ENOUGH TO SAVE OR LOAD A PROFILE.

Oh. MSI X570 Gaming Edge Wifi with latest firmware....for a while i though nahimic had something to do with the problem, but again...clean install, onboard audio disabled in bios prior to windows clean install.

Happening to me as well. It's clearly a bug in this library


I purchased Dolby Atmos Headphone a long while back, I've had to disable THX and revert to that for some decent form of simulated surround. If they fixed it, or worked with MS to fix it if it's some other issue in windows spatial plugin support, I'd switch back in a heartbeat. I agree with one of the comments above that an ACK of the issue and a "we're looking into it" would be cool. I would imagine they know it's happening though.

They do know about it for sure and just don't want to look into it, or admit is an issue with the .dll file. I have gone back and forth with a Razer Level II Technical Support Representative over this issue for several weeks and they are basically telling me the Dev Team is passing it off as being caused by some external factors. Below is one of the last responses I received back from Support.

"Good day!

Thank you for patiently waiting for our email and we apologize for the delay.

With the information that you have provided, and after carefully attempting to reproduce your issue, our Development Team identified that the behavior of your software is caused by external factors outside of our team’s means. This means that there may be third party software installed or corrupted files on the operating system that is affecting your Razer Software to behave this way.

Below are some of our steps that you may want to perform that might help you rectify the issue. Please note that pursuing any of the below steps is totally up to you as Razer will not be liable for any Data Loss, Data Corruption, or any effects that would result by performing any of the steps below. Also, do note that these steps are not guaranteed a fix to the issue, it is recommended that you should keep your Razer Software up to date.

1. Uninstall/Reinstall Synapse (Recommended)
2. Install/Uninstall any latest Mac OS or Windows Update
3. System Maintenance
4. Reset/Reinstall/Repair Operating System. (Only recommended for Razer Systems; Razer Blade etc.)

Thank you for cooperating with us and please feel free to keep us posted."

This is despite me explaining multiple times that the issue is reproducible on a fresh windows install with nothing but Windows and Synapse 3. I've even pointed them to this thread to show it is not an issue isolated to me alone and that there are at least 8 people in this thread alone that have noted this issue and the only commonality among us is we have a Razer BlackShark v2 Pro. Not to mention the 1,172 or so people that have viewed this thread that likely have this issue as well, but haven't commented on it.

I have pretty much given up at this point and just set the default sound device to the Razer BlackShark V2 Pro device entry to avoid the error and don't use the THX Spatial Audio device at all.

I bought my Blackshark V2 last year, and just now getting the same issue, thinking of buying another pair of headset since razer's support is no use

The same problem, but I can't say that it solves something, the feeling is just a notification.

I got the same issue AUDIODG.EXE/THXSYSVAD2APO.dll keeps crashing

The whole software delivery from Razer have been a complete mess for my part...Synapse not opening/working half the time, THX.dll keeps crashing ect...


@Flexo_3370318

Just to get a clear idea of your "fix"

Disable THX in Synapse?



Set sound device to Razer USB Card and not THX ?



In sound properties you again set Razer USB Sound card as standard unit and standard communication unit?



Do you also disable THX, in sound properties?

I didn't even have to disable THX in the Razer Software. Simply changing the default in the Sound Control Panel in Windows to the Speakers Razer BlackShark V2 Pro as the default Sound device stopped the THX errors occurring and showing up in the reliability viewer.

I can't speak to the other issues you've been having with the Synapse Software I have been lucky in that regard as to not be experiencing any other than the THX issue.
