/usr/bin/play -- not found in one instance of 19.04 but found in another

I have three machines with ubuntu 19.04 MATE and only two have /usr/bin/play.

All three have Intel cards.

What's up?

If I got your problem correctly - you mean /usr/bin/play from sox package.

As it is a deb-package then it was installed as dependency for some other package.
You can check exact package name using Aptitude on system with /usr/bin/play installed:

sudo apt-get install aptitude
aptitude why sox

On my Ubuntu 16.04 LTS system the sox package was installed as dependency of K3b:

$ aptitude why sox
i   k3b Suggests sox

Yup.

apt install sox

Just the thing.
