Re the hifiberry digi/DAC issue.
I've done some digging and based on the error messages produced it seems that it isn't the hifiberry's drivers that produce an error but instead the wm8804 codec and its use of core.c (the voltage regulator).
I've been digging through popcornmix's kernel repository but have been unable to find any obvious changes to either the wm8804 codec sources or core.c which might have led to this issue - do you know of any changes in these other subsystems (or in which they may depend) which might have led to this regression?
Best regards
The base OpenELEC kernel config is here, although I've disabled some options that I believe are related to the now removed Wolfson driver, so the kernel options I am currently using can be seen here.
Typically, kernel options are automatically selected by "make oldconfig" as part of the kernel build process, but it's entirely possible that the correct/required options are not being selected (possibly due to a misconfiguration in the code, or a change in the way options are handled in 3.17.y). What's frustrating is having to work this crap out on behalf of a vendor that is showing total disinterest in supporting their product.
