wineasio provides an ASIO to JACK driver for WINE. ASIO is the most common Windows low-latency driver, so is commonly used in audio workstation programs. (Wine's built-in JACK transport isn't a Windows ASIO driver.)
I've just uploaded a new tarball with the latest code from HEAD to make it easier for people who prefer that vs SVN.
This version has a number of changes that address possible performance issues. However, can I ask that if you're having xruns with 0.7.x, you try 0.5. If you don't have xrun with 0.5, please let us know.
