Creative sound card 5.1 Audio output support in Windows 11

Hi Ice,
The shortest answer, would probably be a simple and straightforward No, since FxSound was made with stereo setups in mind, and there are no explicit options to configure 5 or more separate speakers anywhere within FxSound; so if you are looking for a program to do specifically that, I would not recommend FxSound.
FxSound’s owner James posted this on the topic of Surround Sound:

That being said, there is an option within FxSound’s “Configure speakers” dialog box to set the device up as either a stereo system, a 5.1 system, or a 7.1 system (see below); but, while changing the configuration actually does the trick for some people, it just as often fails to work for others.
It also seems worth mentioning that several forum members have found different and sometimes quite counterintuitive solutions for their particular problems, like switching to Mono or setting the default frequency format to 24/96.
You’re welcome to run a forum-wide search yourself anytime on the topic of Surround Sound by typing in the desired terms into the little magnifying-glass box at the top right of the forum.
Either way, if you do decide to install FxSound, then make sure to take a look at my standard troubleshooting list at the top of the forum, which includes some basic yet essential tips for setting the software up correctly, such as disabling Enhancements and Exclusive Mode.
