Can you provide a one-sentence description of what an "earcon" is in this
comment for code readers who may not know?

[lisayin, 2014/07/28 20:31:27]

Done.

 Sorry I added it to the wrong file. I will add it to this file as well.

I'd also be fine with just calling it "sound" here. Earcon is a term we use only
within screen reader code and documentation. (It's a play on the word "icon")

+  virtual void PlayEarcon(int sound_key) = 0;
+
   // Initiates play of shutdown sound and returns it's duration.
   virtual base::TimeDelta PlayShutdownSound() const = 0;
 };
