Dell Optiplex 7040 Realtek clicking popping audio sounds

Looks like the latest audio driver from Dell has fixed a sound problem where you could hear clicking and popping, sometimes interference, sounds whilst playing music or adverts. It was most obvious on Spotify. This is using the built-in Realtek Audio hardware.

Previous driver was dated 12 Aug 2016 and the update is dated 19 Dec 2016, listed as Dell revision A07. Download Audio_Driver_RT1XX_WN32_6.0.1.6117_A07.EXE 

Worth noting the Dell Command Update utility (v2.3.1) for checking if updates are available, didn't list this particular audio driver update for download. We only spotted it when manually checking the Dell support website.

(Just for completeness - we'd also loaded BIOS 1.5.10 dated 9 May 2017 at the same time, but don't think that was relevant. There was mention of a LAN driver possibly causing audio interference, this system was already on the latest Dell download 20.4 A01 with driver dated 5 Oct 2015 for Intel l219-LM. Intel have a newer release 22.3 ProWinx64 with driver dated 19 Mar 2017. Hyper-V and VMware virtual adapters were present)
