I just downloaded Audacity 3.7.4. And no matter the settings I tried, I get NO playback for .5 seconds. That includes any music selected part that’s over .5 seconds!
Sorry It turns out that all my audios does this 
Even videos. Audacity just show the problem more visually. I got a “new” computer 64bit, intel core i5 and have win 11. No telling what the real problem is.
