I apologize for the late response. I tried to check my sound driver list but I'm not certain which one is the sound driver. But I think it's one of these:
- Intel(R) Display Audio
- Intel Smart Sound Technology (Intel SST)
- NVIDIA High Definition Audio
- NVIDIA Virtual Audio Device (Wave Extensible) (WDM)
- Realtek(R) Audio
Furthermore, the connection is with the wire that I got from the product, it's the USB wire.
For buffersize I have tried all kind of combinations but only at the lowest (480~ samples) is there almost no delay. However anything higher than that, and I get a massive delay. Even though the program says it is only around 40 MS delay, it lasts around 400 MS.
