Hi,
Thanks so much to all who have shared on this post.
It greatly helped me and my community (the piano sound had been suppressed on a Windows 11, HP Envy) .
I created a resource summarising the workarounds listed on this forum for my community - feel free to share if it's helpful.
Special thanks to Lenka, Erop, Paul, Robyn, Dorset, AYMAIA and Robbie.
