Added calling of the stream_analog_level api in audioproc_f

Added calling of the stream_analog_level api in audioproc_f

The test program audioproc_f does not call the stream_analog_level
method. This should be done do
1) Ensure that proper log output is produced when reproducing a call.
2) Ensure that this method is properly tested.
3) Ensure that the correct side-effects are triggered (this method
   is not const).

LGTM. I don't see any side-effects or log messages in the definition of
stream_analog_level(). Is that something that may change in the future or am I
looking in the wrong place?

Currently, the only side effect is the logpoint that was recently added. From a
code-security perspective though, the method is not const, so there is nothing
stopping a side-effect being introduced by mistake. Furthermore, calling this
method allows verification in offline tests that the value returned is
initialized, i.e., that the method does not read an uninitialized variable.
