I have been using the firmware file for more than a year without any problems on 3.14.23, so I assume it is v1. I don't know why the driver tells me it's v2, however. Maybe my tree is messed up. If I port adau1701.{c,h} and sigmadsp.{c,h} from 3.14.23 to 3.18.3, it works. I think I have to look deeper into that... > The patch[1] that adds support for v2 is pretty standalone and you > should be able to backport it to v3.18. If I cherry-pick that in, the message is gone, but still, I don't have no output. > [1] > http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/sound/soc/codecs/sigmadsp.c?id=a35daac77a0397d4f23b642d3dc0684682e56cc5
