Z97-Gaming 5 Soundblaster cinema 2 Issue

[jackooze]

Hello everyone, this is my first htpc build and I ran into a software problem and hope someone here can help.

Hardware:
Intel i7-4970k
16gb crucial 1600
Samsung 250gb

So basically I have a monitor and flat screen connected to the pc. I have two standard speakers connected to the rear audio jack when using the monitor. The flat screen is connected to an Onkyo receiver that has an hdmi coming from the motherboard pc. My issue is with Soundblaster cinema 2 only recognizing the speakers connected to the rear audio jack. I want to use the on board sound card for 5.1 audio and not the windows default HD audio. In sbc2 when choosing change default audio device I get two options - speakers(Realtek audio) & windows default. When testing SBC for audio out of the receiver not works except the windows HD audio. After doing some research before writing on this forum I tried re-installing SBC2 and Realtek driver with no change. Can someone please give me some advise on how to fix this issue.

Thank you

Did you try right click under Sound--Playback, and check "Show Disabled Devices"?
Did you install onboard Chipset Drivers?
Can you select anything under Sound--Playback--right click Realtek Audio and then choose "Configure Speakers"?
What does Realtek Audio Manager show?

Does the Onkyo receiver need driver?
Is it well function with another pc?

Yes I tried to view any disabled device and non there. I only have two option "High Def audio & Realtek High Def audio". Realtek High Def audio 6.0.1.7293 is the latest onboard audio driver for the motherboard. I could configure Realtek to 5.1 surround but how come the Soundblaster wont work.

So..you connect the Onkyo to the mobo using HDMI cable, and what cable do you use from Onkyo to the flat screen?
If both are HDMI then I think it should be fine:
You should make sure your Onkyo is right set as HDMI mode, Motherboard on board HDMI port---->Onkyo HDMI in--->another HDMI out from Onkyo---->TV
Remember to restart the system before you can use, then you can see your TV device under Playback, configure the device then select 5.1.
