How do I change Realtek HD Audio 2nd output?

[jorryrojer]

Hi guys,


I'm having a little problem with my onboard audio, having just installed Windows 7. I have an Asus B85M-G motherboard, which includes a "Realtek® ALC887 High Definition Audio CODEC" onboard.
I have installed the latest realtek drivers; R2.79 from the official website.


Now, here's my problem: when I was using Windows 7 on this same machine, I could plug headphones in the front panel connector, as well as speakers in the green back panel connector. This would give me two audio outputs in the Realtek Audio manager, which was pretty practical and enabled me to output different applications through the speakers or the headphones.


Now, however, there's only one output, irrelevant of whether or not I have two outputs plugged in at my computer.
so, I tried change setting to used 2nd output function, but I don't find "Playback Device -> Make front and rear output devices palyback two different audio streams simultaneously" Tab in the option.(ver 7001~Last version)(see 2nd picture)

I want a visible the check tab(3rd picture)

If clean uninstall (sorry don't know how to for Realtek) and fresh re-install does not work, try an older version instead of R2.79 - latest is not always the best especially with older hard and software. I know guru3d has them in their download section.
