We say that English is "right-headed" for this reason - an audio subsystem is a kind of subsystem, not a kind of audio.
Interestingly, there are a few established words, derived from verbs, like kiss-ass or pickpocket which have things the wrong way around; the prediction from right-headedness would be pocket-picker.
...none of those make any sense. Chrome isn't for Google. It's made and distributed by Google. iPhones aren't for Apple. Office isn't for Microsoft.
What were you trying to say?
Windows subsystem for Linux is a product. Just like Apple iPhone is a product. Just like Apple iCloud is a product. Nobody names their products with their company name at the end.
The equivalent of "Apple iPhone" is, in this case, "Windows Audio Subsystem". Not "Windows Subsystem for Audio".
