I received the notification yesterday my Device wasn't quite ready yet, but as soon as it was, I would be able to take the download then.
Right now, I have Windows 10 Home, version 1909, build 18363.836.
I have an Inspiron 15 R (Inspiron 7520)
3rd Generation Intel Core i5 - 3210M 2.5 GHz (3M cache up to 3.10 GHz)

Got this info from Device Manager
Conexant SmartAudio HD Driver version 8.54.37.0 Driver date 4/05/2012
Intel (R) Display Audio Driver version 6.16.0.3154
I went to Dell and searched for the latest driver for Conexant Smart AudioHD for my laptop using my service tag number. There was another driver available as of 5/15/2016.
I downloaded the driver and it installed successfully. I then had to restart my laptop. When I was back on the desktop, it no longer showed the Conexant SmartAudio HD where the speaker icon is on the taskbar.
I went to the Device manager, and Conexant SmartAudio HD was no longer listed. I also have Logitech USB External Speakers, and the drivers for that was listed.
So I still had volume through the USB external speakers. However, the microphone no longer worked, because it required the Conexant SmartAudio HD in order for it to work.
I had to do a system restore, and that worked. So I still have the driver version 8.54.37.0. I don't know why updating to the latest driver made Conexant SmartAudio disappear, however.
I did just read at Micorosoft that they were working with Conexant SmartAudio HD to try and solve the problem. I guess that means that I will have to wait until the problem is fixed and then I'll be able to download the upgrade to version 2004 through Windows Update. At least, I hope so!
