Hi,

I'm trying to get audio working on the Weibu F3C miniPC which has a 3.5mm headphone jack and 3.5mm mic jack. The SoC is Intel Cherry Trail x5-Z8300.

The ES8316 codec included is not supported by Linux at the moment. I'd like to fix that and upstream the driver but so far am I stuck with no audio output, only silence. I do have a working Windows setup that I can poke at for more info.

I would appreciate any suggestions or ideas. Here is a description of my efforts so far, followed by the work in progress code:

I started with the Cherry Trail ES8316 platform driver + ES8316 codec driver which I found in https://github.com/JideTechnology/remixos-kernel/tree/jide_chuwi_vi10_plus_r...

First I did the required updates to get it building on Linux 4.9 including adding the driver for the codec's MCLK input which is done with some patches currently under review:

clk: x86: Add Atom PMC platform clocks arch/x86/platform/atom: Move pmc_atom to drivers/platform/x86 platform/x86: Enable Atom PMC platform clocks

I confirmed that I am manipulating the right clock by disabling it under Windows and observing that audio output suddenly stops.

I created an audio loop within the codec itself, by enabling MIC1 as an input to the Left HP Mux, enabling the LLIN Switch, and enabling Left HP Mux as an input to Left Hp Mixer. Now when I make noise in the microphone, I can hear it on the headphone. This verifies that most of the audio path through the codec is working fine, and also that it is clocked.

I used asoc debugfs to trace the path through the DAI, platform and codec DAPM graphs. Everything is On and active as expected. I confirmed that it is basically the same as another Cherry Trail platform I have here (except for the codec which is rt5645 on the other platform), including mixer levels.

I also dumped the codec registers over I2C from Windows and set them to the exact same values on Linux. Still not working.

At this point I am suspecting that this is likely a problem with the audio interface and its linkage to the codec (SSP/I2S).

I modified the platform driver to use ssp1 instead of ssp2, because the device schematics say that I2S_1 is being used. Then I ran into send_ssp_cmd() complaining that ssp1 is not supported, and found a point of curiosity here. This code is basically to set the value of sst_cmd_sba_hw_set_ssp.selection which is documented as: /* 0:SSP0(def), 1:SSP1, 2:SSP2 */ But other platforms like cht_bsw_rt5645 use ssp2, for which send_ssp_cmd() will use SSP_CODEC, which has value 3. So it looks like the above comment is wrong? Either way, I tried selection values 0, 1, 2, and 3, and still no audio output.

Here's the code, apologies that it is a bit unclean, I'll continue improving it once I get something working. Any suggestions, or do I need to get a hardware scope to diganose further? --- drivers/base/regmap/regmap-debugfs.c | 2 +- sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/es8316.c | 1386 ++++++++++++++++++++++++++++ sound/soc/codecs/es8316.h | 124 +++ sound/soc/intel/Kconfig | 12 + sound/soc/intel/atom/sst-atom-controls.c | 5 +- sound/soc/intel/atom/sst/sst_acpi.c | 2 + sound/soc/intel/boards/Makefile | 2 + sound/soc/intel/boards/cht_es8316.c | 1462 ++++++++++++++++++++++++++++++ 10 files changed, 2999 insertions(+), 2 deletions(-) create mode 100644 sound/soc/codecs/es8316.c create mode 100644 sound/soc/codecs/es8316.h create mode 100644 sound/soc/intel/boards/cht_es8316.c
