Hi all. Having some trouble w/ onboard audio on my new motherboard. I used to use my Titanium HD in my old setup. My problem is I like the "virtual surround" I get from 2 channel sources (Youtube music, ect). With onboard Realtek HD, I don't get anything out of the rear or center channels, on L/R and subwoofer using 2 channel sources. I had it originally connected via Optical SPDIF to my Logitech Z-680s. Only tried a couple games using this setup, Dead Space and BF4 worked fine, but no surround in Alien Isolation though I attributed that to a bug as other people had the same gripe. I tried using DTS:connect, no change. When set to optical output in sound manager, no speaker config. options are available. After some google investigating, I read that it could be the Optical cable/config w/ realtek causing the problem. However, same optical setup, same speakers w/ my Titanium HD worked fine. Anyways, I've since switched to the 3 3.5mm analog setup. Now using analog 3-wire setup, I can adjust speaker arrangement. Speaker test works fine for all speakers. I tried Alien Isolation, now surround is working great . However, still no upcoverting of 2 channel stereo Youtube to surround. I tried DTS:Connect again and the DTS Ultra PC II settings to no avail. Is this setup possible w/ Realtek 1150? I'm using Windows 8.1 now vs. Windows 7 before upgrade if that matters. I'm just curious if this is a Realtek/Software issue or a setting that I'm missing. I'm saying this as like I mentioned earlier my X-Fi HD worked fine in full surround for all games that I played plus upconverting Youtube music. I'd reinstall the card, but won't fit now, GPU Multi-Link blocking slots
