[alsa-devel] Intel Cherry Trail -- No sound in linux

[Zhihe Tu]

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 ?
