A recent idea of mine is to build upon your thread split work and
- ensure at most one player thread is running at any time;
- by adding a wmw->thread slot;
- and stopping a playing thread before the next play or record starts a new one.
This might cause a larger delay when issuing
play mysound; play mysound from 0; play mysound from 500
which would require thread destruction and creation, which is much more
expensive than just bumping wmw->dwPosition (mor or less safely) while another
thread is playing, or starting a new one while the old one is not finished yet
(as is currently done, causing subtle bugs).
What do you think?
BTW, please don't change mciwave now as I still have many patches in the queue.

Jörg Höhle.
