Cubase Elements 10 Playback Volume Glitches

Using Mac OS Mojave 10.14.5 iMac Intel Core i7: After recording a single vocal track, I can see sound wave and by double clicking I hear it with speaker icon when using editor but normal playback has volume glitches. Track will be silent and then loud volume to low volume pLayback. Sometimes the track will not play at all but I can see it and it looks okay. Maybe something to do with the output settings? Anybody know what’s going on?

Disable the noise gate in the insert, or adjust the threshold.
