@Zo - Now I am quite confused. (I understand, by the way, that you are not seeing Sample RATE)
I was NOT talking about 48K (Sample Rate).
I am talking about ASIO BUFFER SIZE, and the values shown in the screen shot you posted earlier are NOT fine, they are quite high (over 500 samples).
I don't understand your post of having a 7.1 round trip latency, when the screen shot you posted up a few posts in this thread clearly shows a total round trip latency value of 28.9 milliseconds, and values for Input number of samples of 522 and output number of samples at 752 milliseconds.
So, did you change your number of samples since you posted that screen shot? If so, then please re-post the current Sonar-reported latency values, like you did with that earlier screen shot, so I can see their current values.
Thanks,
Bob Bone
