3.18 kernel has issues with some high-speed DAC's

Wanted to post to make folks aware of this issue:
which causes some high-speed DAC’s (including my Schitt Modi, apparently) to be unusable.

I’ve been able to fix this issue in Volumio by downgrading the kernel to 3.12, and it looks like the issue will be resolved in kernel 4.14:

So far, Volumio seems to be working with the older kernel, but if anyone knows of issues, please post.
