[alsa-devel] Intel SST and HP ElitePad 1000 G2

[Jorge Fernandez Monteagudo]

Hi,

This is my first email in this list, and my last chance to make my tablet
audio system work

I'm trying to get my tablet audio system working but I'm run out of ideas.
The HP ElitePad 1000 G2 it's an Atom Z3795 1.60GHz Bay Trail-T tablet.

I'm using a kernel 4.2.5 with all the SST configs enabled:

CONFIG_SND_SST_MFLD_PLATFORM=m
CONFIG_SND_SST_IPC=m
CONFIG_SND_SST_IPC_ACPI=m
CONFIG_SND_SOC_INTEL_SST=m
CONFIG_SND_SOC_INTEL_SST_ACPI=m
CONFIG_SND_SOC_INTEL_HASWELL=m
CONFIG_SND_SOC_INTEL_BAYTRAIL=m
CONFIG_SND_SOC_INTEL_HASWELL_MACH=m
CONFIG_SND_SOC_INTEL_BYT_RT5640_MACH=m
CONFIG_SND_SOC_INTEL_BYT_MAX98090_MACH=m
CONFIG_SND_SOC_INTEL_BROADWELL_MACH=m
CONFIG_SND_SOC_INTEL_BYTCR_RT5640_MACH=m
CONFIG_SND_SOC_INTEL_CHT_BSW_RT5672_MACH=m
CONFIG_SND_SOC_INTEL_CHT_BSW_RT5645_MACH=m
CONFIG_SND_SOC_INTEL_CHT_BSW_MAX98090_TI_MACH=m
# CONFIG_SND_SOC_QCOM is not set
# CONFIG_SND_SOC_XTFPGA_I2S is not set
CONFIG_SND_SOC_I2C_AND_SPI=m

I've follow the same steps as the installation for Asus T100TA
https://wiki.debian.org/InstallingDebianOn/Asus/T100TA

and finally I only get the dmesg traces:

sst-acpi 80860F28:00: No matching ASoC machine driver found
intel-sst-acpi 80860F28:00: No matching machine driver found

From the 'dsdt.dsl' I can see:

What am I missing? I suppose I need some changes in the kernel sources but I don't know
where to start. Any help is welcome
