I can't reiterate how dumb sound cards are without an HDMI output for Dolby TrueHD/DTS MA bitstreaming or PCM 7.1 uncompressed output. When your entire graphics card is outdone by Intel's HDMI sound features, you know your product sucks. I know, some people have really expensive headphones that they need to drive (and justify their purchase of), but USB DACs appear to do that in a smaller, cheaper package. If you output sound from this card to a receiver, then you have already gone analog in the transmission of the sound, and missed out on Dolby Atmos, DTS:X, any receiver processing of bitstreamed formats. Essentially, you ruined it.
Sound cards are dead. The only thing Creative still has over the gaming community is EAX support for older games, which prevents a lot of classics from outputting surround sound, or the games are missing audio features. Any new game will work fine with any GPU audio out, as long as you send it directly to a receiver or soundbar or HTIB without going through the TV. If you MUST go through the TV, then you can probably use your motherboard's SPDIF (optical out, TOSlink, etc) and if your board is halfway decent, then it probably supports Dolby Digital Live or DTS Interactive in order to crunch 5.1 surround sound into a bitstreamable format.
Honestly, sound on PC is a mess. And that's why sound cards could actually have some utility! But they routinely leave out the one feature that would make it worthwhile: HDMI output. Without that, might as well stick with the other options.

Which card did you need drivers for, if you don't mind me asking?
