Anyone using Xonar Essence ST sound cards?

I stumbled upon a PR [1] a few days ago about a driver for those sound
cards. The author was not interested in working on it any more, as he
does not own those cards nowadays. Looking at its code, it seems like a
relatively old codebase, so I suppose it should be working fine.

If any of you owns a card like this, please let me know. I would be
interested in importing this directly to the base system, instead of
letting it rot in the PR.
