ISSUE TYPE

• Bugfix Pull Request

COMPONENT NAME

ansible/modules/notification/osx_say.py

ANSIBLE VERSION

ansible 2.2.0.0
  config file =
  configured module search path = Default w/o overrides

SUMMARY

The voice paramater is not required and the current default fails on macOS Sierra. Alex is a safer default as it's persisted across versions up to this point.

**Playbook:**
# talk.yml
--- 
- hosts: localhost
  connection: local

  tasks:
    - name: osx say something
      osx_say:
        msg: '{{ inventory_hostname }} is talking'

**BEFORE the fix:**
$ ansible-playbook talk.yml

PLAY [localhost] ***************************************************************

TASK [setup] *******************************************************************
ok: [localhost]

TASK [osx say something] *******************************************************
fatal: [localhost]: FAILED! => {"changed": false, "cmd": "/usr/bin/say 'localhost is talking again' --voice=Trinoids", "failed": true, "msg": "Voice `Trinoids' not found.", "rc": 1, "stderr": "Voice `Trinoids' not found.\n", "stdout": "", "stdout_lines": []}

PLAY RECAP *********************************************************************

**AFTER the fix:**
$ ansible-playbook talk.yml

TASK [setup] *******************************************************************
