Problem description

Adding autoplay to a sound file attached to a question will result in the sound playing automatically only of the question is not the first one of the survey.

The problem also occurs if:

• The user navigates to the page using the hierarchy menu

Steps to reproduce the problem

1. Create a survey with a single question that has an autoplay sound. The sound will not play when the form is opened.
2. Add another question in front of the autoplay question. The sound will play.

Expected behavior

The sound should play on the first question.

Other information

The problem seems to happen because the autoAdvancing flag is set to false on the first question.
