[alsa-devel] [PATCH] ASoC: Intel: Skylake: Set sample_type in base config

[Tc, Jenny]

>>sample_type defined in topology configuration is not getting reflected
>>in the dsp param. This patch sets sample_type in base config so that
>>the sample type defined in the topology is reflected int eh dsp params.
>>This issues was uncovered while debugging the S24_LE format which
>>require the MSB byte in 32 bit word to be skipped. Setting sample_type
>>to 1 helps to fix this.
>skl_set_base_module_format() is called from a variety of places, so am I correct in stating that S24_LE never worked with this driver? If so, the patch should really be titled "ASoC: Intel: Skylake: enable S24_LE format >support"

Yes, S24_LE is being enabled for first time, I'll update the title

>Also your commit message is confusing in the last sentence. What do you mean by "Setting sample_type to " when you only use what's provided by the topology?

Yes, setting sample type to 1 in topology firmware helps to fix this. I'll update the commit message to make it clear.
