[SOLVED] <Solved> No 5.1 sound via Optical with Sound Blaster Z SE

I figured it out, while not in the instructions I remember watching some YouTube videos of the device and recall it had ports in the front for your Audio plugs that normally would go to your motherboard, well I took that HD Audio cable and plugged it into the Sound Blaster itself and now I'm getting that sweet sweet 5.1 over Optical!

Thanks for your time!

Hey y'all,

So I just got my Sound Blaster Z SE and installed, I wanted a constant DTS signal pretty much for everything. Per Sound Blaster Command, I select the Encoder DTS, I set the Default Device to Speakers which takes effect into both Command and Windows Sound Control Panel as Command states, I have the Z SE connected via the SPDIF Out line. However no sound whatsoever comes out from anywhere, running the test doesn't work.

Now if I set the SPDIF Out (Sound Blaster Z) I get sound fine but of course at just 2 channels. I saw this topic https://forums.tomsguide.com/threads/5-1-7-1-gaming-audio-via-sound-blaster-z.366895/ but that solution does not seem to work.

Anyone able to tell me if I'm just not understanding how this thing works?

I guess I just feel really dumb. I built this new PC replacing a 10 year old build, that old PC I downloaded an unlocked RealTek Driver and could have DTS set constantly and it worked fine with my receiver however this new I guess RealTek ALC4080 USB drive, I can't use those unlocked drivers and I had hoped just getting this sound card would get me back to what I like and I don't know what else to do.

Thanks for letting us know you solved it!
Of course if you are using Optical, you've eliminated the need for the Soundblaster, it's just acting as a passthru now. Sell it and use the motherbd's optical <grin>
