I am also very disappointed.
My primary machine is an ASUS VivoBook which I got in June 2018. and so frustrating that it has this issue. On Microsoft website there are two issues and it seems I am affected by Issue 1,
Issue 1.
The affected driver will be named Conexant ISST Audio or Conexant HDAudio Driver under Sound, video and game controllers in Device Manager and have file name uci64a96.dll through uci64a231.dll and a file version lower than 7.231.3.0.
I found this file, so I guess for me this is the blocking issue.
UCI64A231.dll7.231.2.0 Conexant Unified x64 Device CoInstaller
Issue 2.
The affected driver will be named Conexant HDAudio Driver under Sound, video and game controllers in Device Manager and have versions 8.65.47.53, 8.65.56.51, or 8.66.0.0 through 8.66.89.00 for chdrt64.sys or chdrt32.sys.
I found these details, which are not amongst the conflicting drivers as reported by Microsoft.
Device Manager >> Conexant SmartAudio HD 8.66.95.69
System32/drivers >> Conexant HDAudio Driver CHDRT64.sys 8.66.95.0,
CHDRT64V64.sys 8.66.95.0
What is surprising is I have another HP laptop from 2011, at that does not have any such driver issues and got updated to Windows 10 2004 release already.
This is so shameful for Microsoft and/or Conexant/Synaptics that they are unable to resolve a code issue in these many months.
