No Audio from left side of REV 7

Mac OS Sequoia.... Serato flashed Driver Update  when plugged in and turned on with REV 7.  Immediately after that no audio would come through the left side.  The waveform shows up as normal on the left deck, waveform looks normal on left Serato Virtual Deck but when you push play on the left deck there is no sound coming out of it.  The waveform plays and looks normal on the left deck  but no audio is registering.  The waveform looks normals on the virtual deck but when the track is playing the waveform looks like the audio is muted or something.  it's dark and all one color, no different colors for the kick drums, snares etc.
