If a control is created in the HAL but not present it will crash the HAL which will crash Pulse.

The initial HAL was created with a USB device presenting a Mic, the version used for CES does not.

The missing Mic control will crash the HAL.

Work around create a HAL with no Mic, for CES, but not a viable long term option (gerrit.automotivelinux.org:29418)
