Hi,
Thanks for your reply.
I've tried to change the fw from fw_sst_0f28 to fw_sst_22a8, but I got an error -16 (obviously the firmware is present :) )
Anyway I followed your suggestions and patched bytcr_rt5651.c this way:

But I still have the same problem: Audio plays slowly.
It seems the DSP is clocked at 19.2, but the system is still clocked for 25, and these changes doesn't seem to have effects...

Hi,
I'm an owner of a 2 in 1 Netbook with an Atom X5 Z8300 SoC with rt5651 codec (Cube iWork 11).
To get audio working I Added these lines of code to the ./soc/intel/atom/sst/sst_acpi.c file:

use the same as for rt5640 on cht:
/* some CHT-T platforms rely on RT5640, use Baytrail machine driver */ {"10EC5640", "bytcr_rt5640", "intel/fw_sst_22a8.bin", "bytcr_rt5640", NULL, &chv_platform_data },

Then i added the UCM files linked in these archive: https://github.com/plbossart/UCM/tree/master/bytcr-rt5651
With this configuration, audio seems to work, but is 'slow': Playback speed is at slow motion, and seconds move slowly (Tried with aplay and audacious with many sound files, using directly Alsa and Pulseaudio with no differencies).
This seems to be a DSP Clock problem. Have you got any suggestions to solve this problem?
we've had this report before with rt5640 but it's unclear what might cause this. the codec is configured as slave and uses the bit clock as source for its PLL. the easiest fix in this case would be to use the 19.2 MCLK which is enabled by default on CHT, see examples in cht-bsw-rt5645 (look at platform clock control and everything with set_sys_clk, but keep the 2 slots). We will add this on baytrail as well at some point when we have a clock framework driver for the MCLK control.
