To fix the "no audio output device is installed" error on your Dell Inspiron 14 5000 2-in-1, you can try updating or reinstalling your audio drivers, running the Windows audio troubleshooter, or checking sound settings and making sure the correct device is selected. If the issue persists, you might need to check for Windows updates or consider using the generic audio driver.

Unfortunately, mine isn't fixed. Let me guide you to Reinstall the audio drivers for your model 

Realtek Audio Driver Inspiron Inspiron_5480

Waves Maxx Audio Service and EQ 

Download both of these drivers.  This audio driver requires the Waves MaxxAudio Pro or Dell Optimizer application to be installed to have full functionality. Give it a try, I guess.
