Hi Pierre-Louis, thanks for your reply.
Yes，I got firmware fw_sst_22a8.bin from http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git -b BSW.
From the source code of cht_bsw_rt5672.c and rt5672.c, the codec should support S24_LE format, but I found S16_LE is the only format that supported by the codec (from the hw_param).
So the format S16_LE issue will influence the sst firmare ?
.............................. Thanks ZH Tu

Did you update /lib/firmware with the latest from http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git ?
