They're still around, I use one because the sound chip on my motherboard somehow failed. I'm allowed to use a subwoofer and 2 sets of speakers I got at goodwill for like 20 bucks. These speakers I use were like 200 dollar speakers back in the 90s so despite them being old they're still good and still work fine. Soundblaster mainly makes the soundcards, granted mines old from 2013 but it works fine on a modern PC. I just checked the site and they made a 2022 version so there's obviously STILL a demand for them, probably because it's hard to get an inexpensive subwoofer unless you buy second hand and it's actually cheaper to buy a separate sound card for 45 bucks and buy used speakers than buy a modern bluetooth or USB one. I saw other more expensive options but went with the least expensive because I needed sound and believe me it's better than the soundbar I used before for music. If you're an audiophile who wants to use your computer as a stereo with older speaker setups? They're still useful. Most prefer headphones now but personally I actually like using my setup even if I was kinda forced into it by a sound chip failure.
