Crystal seems to be usable for me on one machine, but another user
reported back that he was already using the Alsa driver and he still
has the problem so I'm not sure this is a complete solution.

There is a small but growing list of VSTs that fail this way. I am
going to test a few more and see how it goes.

Also, I have opened a bug report at WineHQ to better track this.
Please join in if you have somethigng to add.
