Description
MKRZero
SimpleTone
Other modes are working, but I2S_RIGHT_JUSTIFIED_MODE has a flat data line on an oscilloscope.
Steps to reproduce
Open example SimpleTone and on [line 35](https://github.com/arduino/ArduinoCore-samd/blob/89833081ef18aea430b8943ab653dbbd510d43ce/libraries/I2S/examples/SimpleTone/SimpleTone.ino#L35) change mode from `I2S_PHILIPS_MODE` to `I2S_RIGHT_JUSTIFIED_MODE`.
Connect oscilloscope or data analyzer on SD pin: 9 (Zero) or A6 (MKR) or 4 (Nano)

Research direction
Reproduce the issue in the SimpleTone example at line 35 by selecting I2S_RIGHT_JUSTIFIED_MODE. Observe the SD pin listed for the MKRZero, Zero, or Nano with an oscilloscope or data analyzer, then compare the result with the working I2S_PHILIPS_MODE. Done means right-justified mode produces data on the SD pin.
