Cannot hear short notes when playing

Cubase
1

Hi, I’m using Cubase 9.5 with builtin sound card (Realtek ALC889), Low Latency ASIO driver.
After I draw short notes and click play, I can rarely hear those short notes (its like most of them being ignored), however when I draw longer notes I can hear them but after some kind of a delay.

What is the problem?
Thanks.

Give ASIO4ALL a try. It will probably work better.

Same thing with ASIO4ALL
