Soundblaster X-Fi USB 5.1 THX Settings via Digital Optical

[sten2020]

Hi.

I have Soundblaster X-Fi 5.1 USB installed on my system (Win7) and right now I am using it's analog outs to my computer speakers and I am very happy with it's THX settings (crystalizer, smart volume, etc).

Now, I want to connect my A/V receiver to it via Digital Optical out and I was wondering if I will be able to change the THX settings from my PC via digital optical cable too???

Thank you very much!!!
