es8336: Problems with internal mic detection on Matebook 14 #4757
Description
Huawei Matebook 14 BIOS reports that it has only analog mics:
[ 4.093207] es8316 i2c-ESSX8336:00: PLATFORM_MAINMIC_TYPE_ARG=0xbb
[ 4.093222] es8316 i2c-ESSX8336:00: PLATFORM_HPMIC_TYPE_ARG=0xbb
However, currently, mach->mach_params.dmic_num is not zero when sof_es8336_probe() is called, making the driver to try initializing it. The net result is that the internal microphone is not shown as it is not connected.
I tried to change the logic inside boards/sof_es8336.c to not rely on dmic_num, but this is not enough, as not initializing dmic causes another error:
