I have a Scarlett i2i 3rd gen and I use sonar. When I play guitar using ASIO driver mode, there's lag and crackling. So I use WASAPI, which has less lag and no crackling. But isn't there a way to eliminate the lag completely?

Also, there are times when no sound is detected by the VU meter, even though my audio input and output are correct, and the sound card is receiving the sound, because the light ring activates when I play the instrument. Do you know what could be causing this? I uninstalled Cakewalk and the sound card itself, and the problem was solved. However, it persists and keeps coming back.

I have a Focusrite Scarlett i2i to which I connect an electric guitar.

In the preferences, under audio, in driver settings, the "ASIO4ALL v2 not connected 1" option is automatically selected. I tried selecting "Focusrite USB ASIO Input 1," but the previous option re-selects itself automatically.
Changing the buffer size in the driver settings has no effect on latency. And when I click on "ASIO interface..." changing the sample rate doesn't make any difference. It doesn't open the window I'm used to, especially in Reaper.

Also, during the echo, I only hear one side in my headphones.

Could someone please help me?
