do we still need the int types?

The int types are currently used for volume control. The DeviceId's don't have a
1:1 correspondence with StreamType

[tianyuwang1, 2017/02/23 20:25:37]

We can get rid of the int type.  Just use string is enough.  Don't need to do
the conversion.  

[kmackay, 2017/02/23 20:32:00]

Agree, see https://eureka-internal-review.git.corp.google.com/#/c/65141/ where I
did the same thing

[bshaya, 2017/02/24 00:17:06]

I'm leaving this for now, since Ken is already removing the int types in his CL.
