That sounds to me like some audio connection is being prematurely closed, i.e. it isn't waiting for all of the sound to be played.

>As far as I understand, the reason why I hear this popping instead of

If there's no PC speaker then I wouldn't think you'd hear any kid of sound. The fact that you're hearing a sound, to me, means that there's a working speaker.

>Is that right?

It's impossible for any of us to guess.
