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:
 
--- ./soc/intel/atom/sst/sst_acpi.c.old 2016-05-31 09:05:40.045682194 +0200

                                                &chv_platform_data },

        {},
 };
 
+
 static const struct acpi_device_id sst_acpi_ids[] = {
        { "80860F28", (unsigned long)&sst_acpi_bytcr},
        { "808622A8", (unsigned long) &sst_acpi_chv},
 
 
 
 
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?
 
Thanks,
Pietro
