Audio scrubbing

I've been searching all over the program, but I can't figure out how to turn on the audio when I scrub the timeline.

In other words, when I move the playhead back and forth with my mouse, I want to be able to hear the audio from where the playhead is at.

Currently, I can't do that.

Additionally, when previewing on the timeline, sound only comes out when the playhead starts on the beginning of the audio. Like when I'm in the middle of an audio clip and hit enter, I can't hear it. When I'm at the beginning of a clip and hit enter, I can. Then the sound plays until the end of the clip, and it doesn't stop even if I stop the playhead.

Is the Sync box set to "stream" in this sound's properties?

Ah, how obvious. Thank you very much.
