kernel module snd-soc-sst-byt-max98090-mach.ko.xz was found in /usr/lib/modules/4.4.9-300.fc23.x86_64/kernel/sound/soc/intel/boards/.

But not in /usr/lib/modules/4.6.4-301.fc24.x86_64/kernel/sound/soc/intel/boards/.

Can you share alsa-info.sh from the working and non-working case? I think that driver is supposed to be deprecated in favor of another driver but I can't tell what the replacement driver is supposed to be.

working alsa info is at:

Not working is at:

Unfortunately it looks like the decision was made to not support this module in a distro like environment http://marc.info/?l=linux-kernel&m=147095830801834 . I'm going to close this as CANTFIX unless the Intel developers decide to change their mind or someone reverts it.
