Audio Output Example, different soundoutput when sampleType is set to QAudioFormat::UnSignedInt

Hello

This is pretty new for me, so I'm not shure if I'm right here, sorry if not.

Played with the Audio Output Example. When I changed the sampleType for the audioformat to QAudioFormat::UnSignedInt, the sound I got was different. The only change I made was in audiooutput.cpp. I replaced
m_format.setSampleType(QAudioFormat::SignedInt);
with
m_format.setSampleType(QAudioFormat::UnSignedInt);
The Generator::generateData-function has code to handle both possibility, so I thought, the sound I will get would be the same, which isn't the case.

As mentioned above, I'm not shure if this really a bug or the right place for this issue, but I'm pretty shure it doesn't do what it's supposed to do.

Kind regards,
