trouble with recording lag

Hello,

I have a trouble with recording on Adobe Audition cc 2018.

I generate a rhythm track and when I want to record guitar, sometimes the rhythm lags and it records a silent "pop" into the guitar track.

I´m using AKAI eie pro and laptop HP Pavilion with  Intel i7-7700HQ 2,80GHz, RAM 8GB.

The RAM looks to be used from about 30%, I have a plenty of space on SSD disk.

If there is someone, who can help, thanks a lot.
