I wouldn't count on crying as being an indicator. We have three kids, two of who were at both extremes (one who screamed bloody murder for no apparent reasons, often and for very long periods, as in hours, and never slept through the night, another who almost never cried, went down at 7 pm every night, and slept through the night from day one), and a third who was kind of in between, usually very quiet when put down at night, yet for about a year woke up with what the doctors called "night terrors" but by all descriptions we read of what those are, that is not what they were at all.
All three are on the spectrum, so take it from there.
I don't think crying or lack thereof is any indicator at all.

I'm not likely to be around much longer. As before when I first signed up here years ago, I'm finding that after a long hiatus, and after only a few days back on here, I'm spending way too much time here again already. So I'm requesting my account be locked, banned or whatever. It's just time. Until then, well, I dunno...
