I don't think any major vendor has made ISA sound cards in almost 30 years. Discrete PCIe sound cards exist but I don't know who exactly their intended market is. Audio pros?

You can find old 90's ISA cards used on eBay and whatever. The more sought after types (e.g. SB Pro) may not be exactly cheap, though.

Also, for the retro PC market, there are hobbyist cards such as the PicoGUS. [1]

So, yes or no, depending on what you're asking for.
