Not tested myself, but I think you need something like #13181 too, as not all files include system.h (where HAS_SNDIO is defined).

jenkins build this please

[fritsch]

Jenkins is fine (minus the float issue). I will push that as my PulseRework needs rebasing ontop of this.

Thanks very much @t6 for reacing that fast.
