[SOLVED] No sound from phone-jack via "es8316" on rockpro64

[dukla2000]

OK - still trying to get some noise out of my ES8316. Think I am pretty close but help/suggestions required, please!

I am compiling my own 4.19 kernel: Ayufan versions have no ALSA devices at all. I now have

Code:

chris@rpro64:~$ uname -a
Linux rpro64.dukla.net 4.19.0 #3 SMP PREEMPT Wed Oct 24 10:47:48 BST 2018 aarch64 aarch64 aarch64 GNU/Linux
chris@rpro64:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: rockchipes8316c [rockchip,es8316-codec], device 0: ff890000.i2s-ES8316 HiFi ES8316 HiFi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Which is quite promising. Also

Code:

$ aplay -L
null
    Discard all samples (playback) or generate zero samples (capture)
default:CARD=rockchipes8316c
    rockchip,es8316-codec,
    Default Audio Device

    rockchip,es8316-codec,
    Default Audio Device
dmix:CARD=rockchipes8316c,DEV=0
    rockchip,es8316-codec,
    Direct sample mixing device

    rockchip,es8316-codec,
    Direct sample snooping device
hw:CARD=rockchipes8316c,DEV=0
    rockchip,es8316-codec,
    Direct hardware device without any conversions
plughw:CARD=rockchipes8316c,DEV=0
    rockchip,es8316-codec,
    Hardware device with all software conversions

But

Code:

$ speaker-test -c 2 sysdefault:CARD=rockchipes8316c

speaker-test 1.1.6

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Playback open error: -22,Invalid argument

And then system log fills with

Code:

[   83.424483] es8316 1-0010: No sysclk provided
[   83.425020] es8316 1-0010: ASoC: can't open codec ES8316 HiFi: -22

I did remember 0010 in an error message earlier in the boot:

Code:

$ dmesg | grep ff880000
[    2.090028] rockchip-pinctrl pinctrl: pin gpio4-0 already requested by 1-0010; cannot claim for ff880000.i2s
[    2.090907] rockchip-pinctrl pinctrl: pin-128 (ff880000.i2s) status -22
[    2.092501] rockchip-i2s ff880000.i2s: Error applying setting, reverse things back
[    2.093180] rockchip-i2s: probe of ff880000.i2s failed with error -22

So the question - how to sort the 1-0010 | gpio4-0 | ff880000.i2s conflict? Pretty sure this is in the device tree somewhere but have yet to find something obvious.
