speaker_test() sample no longer works

[dpgeorge]

Since the changes to the audio mixer pipeline, the provide speaker_test() sample no longer works.

Thanks @dpgeorge

Yes, I haven't had time to update all the samples - sorry :(

Suggest we deprecate this in favour of the say_hello() function just above it:
https://github.com/lancaster-university/microbit-v2-samples/blob/master/source/samples/SpeakerTest.cpp#L926

Which provide equivalent functionality through the mixer pipeline.

Does that provide what you were looking for?

I actually wanted to use the raw NRF52PWM object, to bypass the mixer and do custom DAC-like output. I don't have a need for this anymore, but that was my reason to try and use speaker_test().

ah, I see - thanks.

Most likely this is simply because the NRF_PWM module being used in the sample is already in use.... When I get a moment I'll flip it to an unused module and test it works ok.
