There are so many official channels to download drivers, there absolutely is no need or reason to download files from private host sites, virus or not. If someone has a lead for a new driver, please...

Thanks for your help.

Yes, Dell driver 6.0.1.7904 in my original post is from Dell using service tag, but it is too new, Dell audio is included.

Unfortunately, Dell audio / Realtek HD audio manager are in driver itself, even installing from device manager, either Dell audio or Realtek hd audio manager will be installed depending on the driver...

Tried, didn't work.

If I use R2.79 driver I downloaded long time ago for another pc from Realtek site, I get Realtek HD audio manager, every thing works except no sound after wake up from sleep.

I tried R2.80, R2.81...

I really don't like the limited and buggy Dell audio with MaxxAudio on my xps 8910, thanks.
