Yes I believe I followed everything you have told me to do.
This is the link correct, if so I guess I should have told you it did not create the 149476
Download this audio driver again.
https://ftp.hp.com/pub/softpaq/sp149001-149500/...
It will create a folder "C:\SWSetup\SP149476"
Run HPUP.exe and continue with the installation.
Is this what you are telling me to download now again? then run the install.cmd?
