[SOLVED] No sound from phone-jack via "es8316" on rockpro64
#1
The environment is "bionic-lxde-rockpro64-0.7.9-1067-arm64.img.xz".(https://github.com/ayufan-rock64/linux-b...m64.img.xz)
kernel is updated to "linux-image-4.4.138-1094". (https://github.com/ayufan-rock64/linux-k..._arm64.deb)


The sound via hdmi is output well.
However, there is no sound via "es8316", but somehow rubbish comes out on the serial console.

Is there a person who has successfully outputted sound via "es8316" ?

Moin!

> Is there a person who has successfully outputted sound via "es8316" ?

Just wanted to say that you are not allone: Same problem here.

Greetings, J.

As a result of various investigations,
These problems turned out to be caused by the kernel side.

The issues is as follows (0.7.9: gitlab-ci-linux-build-67: 4.4.132-1075)
1. "es8316-sound" no sound.
2. "spdif-sound"  no sound.
3. "serial-console output" contains garbage.

All of the above issues have been solved by modifying kernel.

---
*Additional information)
 At currently the newest kernel (4.4.154-1122),
 all sound (in addition to the above, "hdmi-sound" also) can not output.

I also confirmed that it works correctly with the same modification.

I agree with your findings on 4.4.132 & 4.4.154 kernels - what mods do youu apply to the kernel to correct things?
  • ROCKPro64 v2.1 2GB, 16Gb eMMC for rootfs, SX8200Pro 512GB NVMe for /home, HDMI video & sound, Bluetooth keyboard & mouse. Arch (5.19 kernel, Openbox desktop) for general purpose daily PC.
  • PinePhone Pro Explorer Edition daily driver, Tow-boot on SPI, Arch/phosh on eMMC
  • PinePhone BraveHeart now v1.2b 3/32Gb, Tow-boot with Arch/Phosh on eMMC

Just upgraded to 4.4.154-1122 and have the same issue here as well.
#6
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

  Subdevice #0: subdevice #0

Which is quite promising. Also
Code:
$ aplay -L

    Discard all samples (playback) or generate zero samples (capture)

    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.

The problem of "es8316" is quite tough and can not be solved by only modifying "*.dts" or "kernel-config".

For example, your proposal is,
> So the question - how to sort the 1-0010 | gpio4-0 | ff880000.i2s conflict ?

If you fix it, you can surely see some improvement.
However, this kind of modification alone is not enough,
and only the effect of reducing errors from the "boot-log" is obtained.

In order for "es8316" to work correctly, both "dts" and "*.c source-code" modifications are necessary,
and the modification is more extensive (perhaps, more than you think).

Of course, all the sounds "es8316" / "hdmi" / "spdif" are working.
However, sadly, "mainline-kernel" has not yet implemented "video-accelerator" (mpp related),
it is not fun even if only the sound comes out.

So, I usually do not use "mainline-kernel".

So you mark it as "SOLVED". Could you kindly point us to the solution? Diffs or so... since that comes to modifying kernel source as you've mentioned.

For example, your proposal is,

If you fix it, you can surely see some improvement.
However, this kind of modification alone is not enough,
and only the effect of reducing errors from the "boot-log" is obtained.

In order for "es8316" to work correctly, both "dts" and "*.c source-code" modifications are necessary,
and the modification is more extensive (perhaps, more than you think).

Of course, all the sounds "es8316" / "hdmi" / "spdif" are working.
However, sadly, "mainline-kernel" has not yet implemented "video-accelerator" (mpp related),
it is not fun even if only the sound comes out.

So, I usually do not use "mainline-kernel".

I understand, i need to modify sound/soc/codecs/es8316.c 
Can you tell me which other files i need to modify?

Can you share your asound.rc file?
