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.
I don't know of such a problem, and I can't think that such a long delay happens in the hardware side.
Which sound backend are you using? Does the same delay happen even if you play directly via aplay with -Dplughw?
