/*
 * When the TonePort is used with jack in full duplex mode and the outputs are
 * not connected, the software monitor produces an ugly noise since everything
 * written to the output buffer (i.e., the input signal) will be repeated in
 * the next period (sounds like a delay effect). As a workaround, the output
 * buffer is cleared after the data have been read, but there must be a better
 * solution. Until one is found, this workaround can be used to fix the
 * problem.
