Music v 1.2.4.3 playback is warbled garbled flanged sounding

I am having a very strange problem. I have 2 old Macs with iTunes. My track plays fine.

When I play it on my newer Macbook with Music, parts of the song with a synth sound warbly and garbled, like it is being run through a flanger. Most of the rest of the track plays normally. Weirdly, it transfers this sound to my iPhone when I sync it. If I send the track from the old Mac as an MP3 in a text message, it has the same warbly garbly issue.

I have tried the AIFF, MP3 and AAC versions of the track and they all do the same thing. Has this happened to anyone else? I tried searching for solutions but didn't find one.

MacBook Pro (2017 – 2020)

I figured out the problem, but it doesn't really explain why tracks play differently on new Macs vs. old Macs.

I recorded a bunch of tracks using a 30 year old MXR Stereo Chorus pedal. While this sounded fine on my 2015 Mac, the new Macs played the same tracks with warbly, fluttery sound.

The solution was simple. I had to go in using the phase adjustment utility tool in Ableton and adjust individual tracks on a new Mac. Some tracks needed 0 width to sound normal and some sounded fine at around 20-30% width.

Why old Macs sound fine and new ones play with phase issues is very strange.

Update: If I tick the box in Accessibility "Play stereo audio as mono" the issue disappears, although the track is playing in mono. As soon as I uncheck this box, the warbled sound issue returns.

Again, this happens in Mac OS and iOS.

NVRAM restart did not help, which seemed unlikely anyway because the problem is happening on my phone and laptop.
