Specs :- Asus Z170 Pro Gaming Creative 7.1 Speakers (only front 2, Centre and Bass plugged in due to space constraints) Onboard Realtek HD Audio (Rear - usual 3.5mm connectors) Front Panel 3.5mm headset and mic Turtle Beach X12 Headset Asus HD Audio manager. Windows 10 Firstly I'm a real noob when it comes to sound settings. I have very little clue what the different "Devices" do or many of their settings. No idea what "Stereo Mix", AC97 "Line in", "Default Devices", ... are. So please be patient. What I'd like to do is tell the computer to play all the sounds through both the front panel and the back panel so I can get the same sound from both speakers and headset simultaneously. I have tried every conceivable combination of the settings but even when I Eventually get it to work, it stops working on reboot or if I unplug and replace any of the jacks. I've even resorted to "lying" to the computer when I plug a jack in to say I've plugged a "speaker" in the front panel when really its my Headset but the PC always seems to be 1 step ahead of me forcing it not to work! Can anyone explain PC sounds, devices and drivers basically and let me know what BIOS, devices, defaults and software settings I need to select to achieve this? Its working as I speak with the settings in the picture but it wont on reboot (and telling it to "Play different streams" hasn't worked before either) Many thanks.
