It is not odd at all.

Comparing to the original code, play-sound blocks the current thread to force you wait until it finished, start-process will folk another thread to finish the work.

You're right.  Thanks.

This is working for me:

(setq ring-bell-function (lambda ()
 (start-process "ding" nil "play" "/home/me/audio/tap2.au")))

Odd that invoking an external program and reading a file
over and over works better but it does.
