Base station chroma V2 + BlackShark V2 PRO installation

I've just received the base station and the headset and by registering them both i have also received the 7.1 surround activation code. I've set up both without many issues although there are a couple of doubts remaining: - So far i am utilizing my headset enabling THX spatial audio having both as default audio outputs while the headset is connected. (is this the correct way of doing it?) - The additional 7.1 surround app seems to be a redundant and exclusive app, if i use that my headset disconnects and THX spatial gets disabled. - Ultimately, when i disconnect my headset, although my main audio output was selected within synapse (fallback device), Win11 keeps seeing the THX spatial as the output in use, though, having no audio from my main speaker (i have to manually select the output every time). Is there a way to work around it?
