Short description of error
Retiming freeze frame does not work for audio strips. It still plays the audio between freeze region. Placing playhead over freeze region the starting the playback will start the audio from start (instead of being silent)

Exact steps for others to reproduce the error

Open default VSE file
Add audio strip
Move playhead to some frame inside the audio strip.
In sequencer do strip->retiming->add freeze frame

Press play. Notice that despite the timing being 0%, I still hear a very slowed down version of the audio (to be fair it's not trivial to "freeze frame" audio)
if you move the current frame to inside the frozen time section of the audio strip, and start playback, the audio is not slowed down at all, but will "jump" when it hits the next retiming key.
With the audio strip selected, do strip->retiming->reset retiming. Press play. audio strip still sounds retimed.

Workarounds tried:

Confirm that doing a View->Refresh All does not fix the problem.
Confirm that deleting the audio strip and then undoing the deletion DOES fix the problem.

I guess, that this is limitation and not super greaat design. Ideally, it should completely stop the audio playback. I think, that I would need to handle this internally by making 2 sequence entries in audaspace.

Not quite sure how exactly this fixes the issue - the sound is playing here after deleting strip and undo. But if it works somehow for you, I guess this is coincidence.
