Thank-you, this fixed the buttons for me, though it did take longer than 20 minutes! Saved my speaker as I couldn’t pair it with my new phone as none of the buttons worked. For anyone looking at this, I didn’t bother glueing the top panel back in at the end (paranoia, want to check the fix) - but as it is recessed it sits there quite nicely anyway. Just don’t use it upside-down ;)
