    With the new DAX drivers, they are no longer eligible to be default Windows sound devices.  The software we use to interface with the Windows sound API, PortAudio, requires that a default playback audio device be present before it will load.  The error you are getting is related to this.  You need to plug in a set of PC speakers or headphones into the PC so the PC has a default playback audio device and the DAX error you are getting will no longer occur.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
