r=me. I had a couple of minor questions, but nothing that needs to be addressed before landing.

Do we use this style of constant elsewhere? I thought we always said "1.0 / 10.0" (for example).

I'm just curious here -- did you encounter raciness with the m_shouldPlayToPlaybackTarget state? Because it seems like the original version should have worked.

Hmm, not sure what I was thinking.

It worked, but the "if (m_shouldPlayToPlaybackTarget)" above means we actually always call "client().setShouldPlayToPlaybackTarget(true)" so I just made it explicit.

Thanks!
