In game audio becomes distorted when changing from Realtek to THX spatial audio - what is wrong?

Question

Using Razer Headphones: Models: Blackshark V2/ Kraken V3 Hypersense/ Kraken BT
Razer software for EQ: Synapse 3.8.428.42117

STR:

1. Have 2 output methods ( Realtek and THX spatial audio )
2. Have headphones connected.
3. During the gameplay change sound output methods between them.

 

Result:

• when changing to THX spatial audio the entire sound/ audio becomes distorted, continuous buzzing

Expected result:

• when changing output methods the entire audio should remain the same regardless of output method
