sound: aif1 <-> ssp2 firmware used was fw_sst_0f28.bin.ssp2 renamed to /system/lib/firmware/fw_sst_0f28.bin no quirks needed kernel used is 4.9 with patches https://github.com/onejay09/kernel.git bytrt5640.state in system/etc/alsa/ was the wrong name (bytcrrt5640.state)
a working bytcrrt5640.state i made by booting linuxium ubuntu. steps: boot linuxium check that the byt5640 folder is added to /usr/share/alsa/ucm run sudo alsactl store and a new alsa.state file will be created in /var/lib/alsa/ also needed was alsa_cr.sh + alsa_cr_spk.sh i added them to /etc/init.d/ and are run at boot time this fixed the sound all files i used can be found here in this build directory /Prebuilt/.
