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

Hi,

I've generated a new kernel, a 4.3.0, only with

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_BAYTRAIL=m CONFIG_SND_SOC_INTEL_BYT_MAX98090_MACH=m CONFIG_SND_SOC_INTEL_BYTCR_RT5640_MACH=m CONFIG_SND_SOC_I2C_AND_SPI=m

and I've downloaded the firmware this repository (I don't know this git is the official one) from http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git

But I have no audio. The firmware is loaded, I see this traces

[ 4.013712] baytrail-pcm-audio baytrail-pcm-audio: FW version: 04.05.13.a0 [ 4.013714] baytrail-pcm-audio baytrail-pcm-audio: Build type: a0 [ 4.013716] baytrail-pcm-audio baytrail-pcm-audio: Build date: Apr 2 2014 14:14:39

but the mapping is not done. In the 4.2.5 kernel I see

[ 4.256939] byt-rt5640 byt-rt5640: rt5640-aif1 <-> baytrail-pcm-audio mapping ok

Both attached.

Another problem. In the working 4.2.5 kernel, when I run my application, a game which plays sounds, in a few minutes the system is totally frozen, in some cases, with a sound looping endlessly. I'm trying to get a kernel trace to debug this situation... Any hint is welcome!

Regards

I've download your t100-v4.3-24bit branch, then I've patched it with my changes and I've deployed it in the tablet. I've copied the bytcr-rt5640 from UCM master branch in the /usr/share/alsa/ucm tablet directory, but after rebooting I have no sound.

Attached you can find the dmesg log and the .config used to generate the kernel, maybe any option has to be enabled...

the .config looks problematic, you can't have both haswell/broadwell enabled at the same time. I only have these options defined:

CONFIG_SND_SST_MFLD_PLATFORM=m CONFIG_SND_SST_IPC=m CONFIG_SND_SST_IPC_ACPI=m CONFIG_SND_SOC_INTEL_BYTCR_RT5640_MACH=m

Also make sure you have a 'recent' /lib/firmware.

Hi,

I've been able to get the audio working in the HP ElitePad 1000G2 tablet. Attached the patch I've used in a 4.2.5 to get it working.

Thanks for sharing and good to hear that you have audio working. I have no idea why BIOS folks keep inventing new (and illegal) ACPI _HID values...

We may need to use the same tricks as in sst-acpi to find out which string to use for .codec_name based on which _HID is handled by the ACPI subsystem instead of a hard-coded value.

Note that we are trying to move away from this older driver to a newer one based on DPCM that would also support BYT-CR devices and MinnowMax Board. It's not ready yet for upstream but if you want to add those changes to the newer version and test it'd be great. See https://github.com/plbossart/sound.git t100-v4.3-24bit and matching UCM files at https://github.com/plbossart/UCM

...

Basically in this tablet the rt5640 realtek audio codec is identified with INTCCFFD. I don't know how to share 'byt-rt5640.c' with two identifiers because I had to change:

@@ -186,7 +194,7 @@ .stream_name = "Audio", .cpu_dai_name = "baytrail-pcm-audio", .codec_dai_name = "rt5640-aif1",

•         .codec_name = "i2c-10EC5640:00",
  

•         .codec_name = "i2c-INTCCFFD:00",
           .platform_name = "baytrail-pcm-audio",
           .dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_NB_NF |
                      SND_SOC_DAIFMT_CBS_CFS,
  
  

but the correct will be to two both of them.

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

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
