STM32L476G-Discovery demonstration application

I am working with the STM32L476G-Discovery board. I am testing the examples applications and I have found an error in the demonstration application regarding to the soundmeter feature.

* With the *.bin file provided in the Binary folder the application works normally. I mean, that you can see in the Display how it changes the sound intensity in dB when it is louder or not.

* but, with the IAR source code project, when you program the demonstration application in the STM32L476G-Discovery board, the soundmeter feature doesn't function anymore, it shows a constant value of 120dB in the Display of the board.

I think again, somebody change something in the code and he forgot to test it. Typical, very typical.

Please, check this error as soon as possible and provide a change in the software to solve this problem.
