Hi all,
 
I´m using my new build with the z390 dark for a week now and there is one feature I'am really missing!
 
I can´t find a way to make sidetone work (hearing my own voice in my headphones when talking) besides the win10 solution which has noticable delay.
There isnt an option for this in the Sound Blaster Recon3di control panel.
 
Is it possible to install the realtek audio driver cus there is an option for sidetone? Or is there another sound blaster software out there which has this feature?
 
Best regards,
Fabian

Not sure I don't think you cannot install Realtek Audio Driver that your motherboard support only Creative and Evga Nu Audio for Headphone!  
Yes you need install both but if you wish to use Headphone then you need install EVGA NU Audio.
 Please read in your manual book pages for NU Audio Pages 116
 For Creative Pages 97 
Sound Blaster Recon3di control panel should be in running bottom taskbar small icon 'SB' see if still there? or go click open start and find Creative folder.
 
 
If problem still there then try run troubleshoot 'Playing Audio' and try choose to set default on SoundBlaster Recon 3di.  
For NU Audio if you want to use Headphone then you need change to NU Audio from SoundBlaster in your bottom taskbar click sound icon will pop up list of select playback Device by click small arrow point up then choose NU Audio.
 
Or try run repair your Creative driver?
 
I hope if this help you? Post us back how getting on

Or install latest Driver here > Creative Sound Blaster Recon3Di Drivers Version 6.0.101.1059
Of course this will include SoundBlaster Control panel and I have on my and so far no issue and sound here is so good 

That appears to be an older driver to me?
I wonder if EVGA is going to update the on board Creative drivers at any point. Checking for updates through the Creative Auto Update check shows unable to detect any Creative Products.

I wonder if EVGA will ever get an update from Creative for this board?
Checking through the Creative Auto Updater it says no Creative product found on my system...

Yeah I have the same but it seem don't work really! I uninstall this update software (Extra Software) I use latest driver from Station Drivers so far is good.
I have notice it now update latest version to 6.0.101.1061 

Yeah but is that an official Creative driver?

I can understand what do you mean but I have check with my Kaspersky protection scan this software so it clean so I have installed here recently so far no problem here! 
EDIT> To be honest that I do not understand why didn't the Creative website do not update driver for SoundBlaster!!!

The onboard creative isn't sold or supported by retail creative operations is why, they provide drivers to partners (evga) to package and release for their systems.

Maybe an add-in audio card?
 
I had issues with the on-board Creative playing rear surround through front center (5.1).
 
I bought a PCI-E to PCI adapter cable and have been using my Auzentech X-Meridian.
 
Works flawlessly, unlike the Creative.

This has been a known issue since the Recon3d/3di released in 2012, see this and this.
 
You would be better off buying a sound card that is designed to do this.
 
I just tested the mic delay on my onboard Recond3di (Z370) and the delay is enough to make you feel drunk.

I apologize for several posts being rejected by the spam filter. I have restored those posts

I don't even have 'fast startup' in my shutdown options.
 
I have sleep and lock and that's it.
