I have the following sound devices:

I have my monitor connected via HDMI and that monitor has speakers. The monitor is:

The sound is working OK, however the problem is that the sound is delayed by about one second compared to the picture on the screen. Most visible/hearable by using Musescore, where a music note is highlighted when it is played. Using VGA and the other sound card there is no delay.
