Looks good to me, no problems with any of the drivers. I think it'd be good to get it in on Monday, as release day is tomorrow, but that's not my call.

Use a thread instead of a timer for greater precision.
Changes since v1:
- Add WARN on failure of Start or GetStreamLatency
- Set lower bound of sleep time to 5 ms
- Change upper bound of sleep time to 2.5x period
- Fixup comment

I like how the most useful part of the changelog always gets stripped out. What's the point of even adding this info here?
Obligatory "Yes I know the error handling I added isn't perfect, and I did fix that in my failure rework patch" here..
