Alarm do not start the music from the beginning

[my_love]

This morning was the first day I used the alarm of my S21 ultra, but it didn't work as I expected.

When I was setting the alarm last night I verified adjusting the volume that the music didn't start from the beginning, but I thought it was because I was adjusting the volume and the system only put the music some seconds ahead.

Today morning the alarm started the music at the same point when I was adjusting the volume, around 35 seconds ahead.

I think it is related to the music I am using, because the first 35 seconds are very silent, but there are sounds. 

The music is "La Grange" from the ZZ Top band.

Is there a way the alarm can start the music from the beginning?

turn off "Play selected highlights only" in the sound picker settings when you select your alarm song

Thank you for the answer, but I am not seeing this option.
When I select my song I only can select to read the time and alarm name aloud, nothing more.

I am using the Clock app, it has a purple icon with a clock on it.

I had to add again the song, just edit it does not show the option "Play selected highlights only".

Now it is ok.
Thank you!
