latency suddenly went from 5 to 7.5

[Dimitri Muskens]

I'm getting confused between sample rate and buffer size.

In Focusrite Control, I can set the sample rate.
In the Focusrite ASIO panel (not part of the Focusrite Control application), I can set sample rate and buffer size.
In JK, in gear setup, I can set the sample rate, or I can select "Match". I've been selecting "Match", but perhaps I should specify?

It seems that no matter what I do, JK will reset Focusrite's buffer size. Sometimes it will also change the FR sample rate. 

What is the optimal combination of sample rate and buffer size? I thought that I previously had 48k/48, but perhaps not.

I'm probably being dense, but can you explain, step-by-step, what you think I should do?

Forget the buffer size. (realy)

Sample Rate or Clock Rate/Speed is what we're trying get working for you.
Like I said before, the 2i2 seems to benefit from using 96k.
So set the FR-hardware to 96k in FC
In JKZ set your input and output(!) to your audio interface/asio driver (so, do not choose "same" at output)
Then set the sample or clock rate to the same 96k in the little drop-down and finish the setup. (so, do not choose "match")

Just for my information. Can you actually read your device latency in the jamkazam user interface?
I've seen many windows/jamkazam/focusrite combinations where the device/audio interface latency is listed as 0.0 (cannot be determined)

BTW - 7.5ms is not too bad. In combination with decent (low) internet/network latency this can still be very workable.
