Harmony 17 - no sound, no waveform

Upgraded to Harmony 17 this morning. Imported sound of all files types (wav, mp3, aif) doesn’t play sound also shows no waveforms. Been troubleshooting this for hours this morning to no avail.

In the Timeline-view, check the Sound button.
Right-click the sound file - Show - Show Sounds.
In the Parameters drag left or right to increase or decrease the waveform-size.

In the X-sheet view, right click the Header - Sound Display - Waveform.
