bug in function readData() at NokiaQTSDK\Examples\4.6\multimedia\audiooutput\audiooutput.cpp example

there is an error in the readData function implementation
at line 138
memcpy(data, m_buffer.constData() + m_pos, chunk);
should be
memcpy(data+total, m_buffer.constData() + m_pos, chunk);

in fact in the while loop it does not advance the pointer to data so that it override the previous sound samples causing rumours in the ouput sound

i started my code from example and i discover it while debugging an audible click/rumours in the sound .
As i fixed it , sound plays clean

just to be sure where in the code ,this is the function
qint64 Generator::readData(char *data, qint64 len)
{
qint64 total = 0;
while (len - total)

{ const qint64 chunk = qMin((m_buffer.size() - m_pos), len - total); memcpy(data, m_buffer.constData() + m_pos, chunk); //BUG m_pos = (m_pos + chunk) % m_buffer.size(); total += chunk; }

return total;
}
