Targeting Tracks is the key to this.
eg Target a track (audio or video) where you wish your clip to be placed in the Sequence ( timeline).
Editing is non-destructive. Whaever you do on the timeline does not affect the source material.
To "untruncate" the audio track (or video track, depending upon what you want to do), make sure that the track is not selected, and then alt drag the tail (or head) of the audio track (or video track) back to its original location. This will not work correctly if the track is selected before you press the alt key.
You can also separtate the audio and video tracks so that they are independent of each other.
This is also the technique to use if you want to slip edit audio tracks
I would expect that the audio clips would just be stacked on top of one another
Not automatically (and rightly so). You have to 'stack' them manually, placing the second clip on Audio 2, or 3, or whatever.
the audio clip always remains shorter than its associated video clip.
Hold down the ALT key when you drag the audio portion.
These are both pretty basic items available in the Help file. I suggest a thorough read before actually using the software. You'll become much more proficient and have far fewer issues.
