Normalized audios can't be interrupted

[lizyn]

When normalization feature is on, anki always waits until audios are palyed to the end before it responds to my keystroke. This causes perceptible laspses for both flipping and going to the next card, if there are audios playing.

By "can't be interrupted" in the title, I do not mean the "interrupt" as in "interrupt current audio when answering" option in anki preferences. Even you untick that option (so that audios become uninterrupted), without normalization of this addon, it only leaves the audio playing after you answer a card, but there is no lapse before showing the next card.

Tested on Anki Version ⁨2.1.42 with the newest Adjust Sound Volume addon.

I tried to reproduce this issue, but audios can be interrupted by pressing a key with normalization in my environment (macOS Big Sur and Anki 2.1.42).

Sorry not to include my system environment, I'm using macOS Catalina 10.15.7.

Maybe this problem is due to a conflict with other addons in my case. I will post the detail here if I find it out.
