When editing and using a “split”, when you drag the edge, you can’t see where you’re going until you take your finger off of the mouse. The if you hit “Play”, the cursor moves but no sound for 3-4 seconds. When you’re scrubbing a clip, it makes it difficult to edit if you can’t hear what you’re trying to hear.
It seems OK here, or is this not what you mean?
Windows 10, Audacity 3.2.4
When scrubbing or anytime you press “PLAY”, the cursor moves for several seconds before the music can be heard.
What settings do you have in “Preferences > Devices”?
