How do you know this? I don't know either way, but superficially it
looks like the wave.py author tried to do "the right thing."

Why don't you at least try setpos, and fix it if there's a problem?
Or report on the problem you _actually_ encounter, which could be useful.
That much can't be much harder than looking for an alternative, and may
inspire others to help make/find a workable solution for you.
