Hi,
I recently installed Arch on my HP Chromebook 11 G4. It has a Baytrail Celeron N2840 chip and with the latest Arch I didn't have sound working. Only the HDMI audio out was recognized but the speakers and headphone audio weren't.
After some digging and looking into the modules loaded in Chrome OS I found that the laptop has a Byt Max 98090 chip and it also requires the snd_soc_sst_baytrail_pcm and snd_soc_sst_byt_max98090_mach kernel modules for it to work. For some reason these modules don't exist in the latest 4.5.4-1 kernel that comes with Arch. Even the testing kernel 4.6-1 does not have these modules. However looking at the source tree of the mainline kernel at kernel.org the code seems to exist.
Also 4.4.5-1 kernel from the Arch archive has all the required modules and sound worked (after a little tweaking with ALSA).
So I wanted to know if there was any specific reason for these modules to be omitted in the newer Arch kernels. If they won't be coming back then possibly I will pull out the sources from the mainline kernel and compile the modules myself to work with the latest kernels.
Thanks.

It seems that a change in kernel settings triggered that, check BR #48936 .
