I have a sram 1071 chain and XT 10 speed rear cassette. I mean I only rode around my neighborhood but it worked great.
Also, the sram 10 speed chains make lots of noise on the shimano road cassettes. I've read that and I experience it on my road bike.
I wonder if it still does with shimano mtb cassettes
In theory, 10-speed Shimano MTB will only work with 10-speed Shimano MTB. I'm sure you can throw anything on there and it'll shift, just not as good as it will using the Shimano chain. I use Shimano chains all the way around because they shift better, feel nicer, and are much harder to break, even when using SRAM everything else.

Are you using the shimano pin or a quick link?
I've done both, but prefer using a KMC Missing Link. I have that set-up on my Sola right now and it came in handy during a mishap at Sourlands last week
