Built in speaker wine

[retro space]

The speaker of the CPC 464 makes a high pitched wine/beep if I turn the volume up to a decent level for playing games. When the games are loading, even from USB on the ULIFAC, I hear what seems like a loading sound as well, faint, but certainly different from the basic beep.
I read that it is caused by the sound trace going through the tape board and catching a lot of signal noise along the route.
Is there a recommended fix to make the sound clean(er)? I have no interest in fixing the tape drive for now, don't want to damage it, but if disabling a part of it helps it is ok.

There is a fix to completely isolate the audio (prevents electronic/tape noise from speaker) but said noise was largely a "feature" not a bug

There's a more in-depth discussion and thread linked below.

I had seen that topic, but I could not distill what to do to fix it out of the messages.
