It took for ever, but at last the speaker crackled.

And a speaker crackled into life somewhere on her desk.

Still, she did not relax until the external speaker crackled to life.

I'd felt about the same, every time the speaker had crackled in the two days since the first muster.

The speaker crackled, just like in the ancient movies and holes.

A speaker crackled to life on top of the cruiser.

A small speaker crackled to life like an ancient radio.

There was a long pause before the speaker crackled to life again.

The speaker crackled, and then they heard the sound of music.

There was a short silence, then the speaker crackled again.
