This patch adds audio codec (Everest ES8316) and I2S audio nodes for

Hi Katsuhiro,

I tested your patch with my rockpro64 on 5.4-rc6 which has your other
patches to es8316 driver, but apparently it doesn't work.

'alsamixer' complains 'cannot load mixer controls: No such device or
address' and if I try to play audio with mpg123 it pretends that it
plays something but there's no sound.

Any idea what can be wrong?


Do you use defconfig? If so I guess we need turn on more configs:

- simple-graph-card driver (CONFIG_SND_AUDIO_GRAPH_CARD)
- ES8316 (SND_SOC_ES8316)


FYI) ASoC related status or logs in my environment as follows:
