Use 7.1 audio without THX - Razer Blackshark v2

I have a Razer Blackshark v2, connected to my Windows PC with the sound card, and with the latest Synapse installed.
I have two options in the Windows sound devices:
"Razer USB sound card" and "THX spatial audio". I personally find the THX spatial audio kind of muffled and I don't like it for the majority of the things I am doing. Is it supposed to sound good for audio that is not 7.1, am I doing something wrong?

Additionally, I am getting a prompt by the Razer Appengine to activate THX, which I have not done since I do not have an activation code. As I understand THX works from synapse, so can I disable razer appengine overall? It is also my understanding that the Blackshark v2 does not come with an activation code for THX, is this correct? Do I have to/can I activate THX from Razer Appengine or is Synapse all I need?

In any case, I prefer to use the "Razer USB sound card" and that's where my main question is.
Razer USB sound card is set up as Stereo and cannot be configured as 7.1. Is there a way to have 7.1 audio configured on the sound card without spatial THX sound, or that's not how it works? Does playing a 7.1 audio file, or a movie with 7.1 sound on vlc for example, with the "Razer USB sound card" as default device use the headset as 7.1, or as Stereo?

I second this, i didn't get any activation code for 7.1 surround nor for the THX Spatial audio after buying and registering my Blackshark V2.

Weird enough, i can use THX spatial but on the top right corner of Synapse, it says that i need to activate my THX spatial within 8 days and that im on trial mode now, even though THX spatial is included in the product i bought....

Razer never disappoints me with their 10 year old product and interface planning.

Where can i get my activation codes for 7.1 and THX Spatial now?

Blackshark V2 comes only with THX Spatial, not 7.1 surround. No activation needed, it's available out-of-box through Synapse 3 software.

Yeah that's what i've figured out yesterday. Thanks.

But one more problem is that on Synapse 3, i have an alert on right top corner, stating: ''You have 7 days trial remaining.'' And asks for activation of THX.

I don't get it, why it asks for activation even though i bought it legit and registered my Blckshrk. V2. product with serial number?

I didn't receive any e-mails for activation either. Can you help me out with this? Thanks.

Probably because you've installed THX Spatial as external app - uninstall it.
It should be only Synapse app installed nothing more.

No, that's the problem. The alert is on Synapse 3 as i said clearly.

Now a support member says that i have to PAY for spatial audio to unlock it even though it stated the app is included with the product, Razer is totally a joke, i will never and ever buy any of their products again.

Do you have any screenshot of the message?
