Hello Vasily,

Hi Katsuhiro,

Thanks for response!

Looks like on my board codec sits at address 0x10, and according to
schematics that's what its address is supposed to be.

See http://files.pine64.org/doc/rockpro64/rockpro64_v21-SCH.pdf

Codec address is selected by pin CE of ES8316, and on rockpro64 it
goes to GND through R226. So address should be 0x10.


Yes, I agree. The schematics both v2.0 and v2.1 say that ES8316
address is 0x10. Thank you for pointing.

But I wonder that my RockPro64 behavior is strange, he is in address
0x11. (R226 on my board is broken...??)

I plan to check R226 resistance value to judge R226 is broken or not
after return to home. And share the result with you.
Please give me a time.

Thanks for confirming that on your board it's on address 0x11. I
checked with some other rockpro64 owners and they have it on 0x10, but
looks like we have boards with codec on different address in the wild.

Another datapoint is that my board is 2.0. If yours is 2.1 it can be a
difference between 2.0 and 2.1.


I'm using v2.1 board.


I'll share the checking result. It's a little strange.

1) Voltage of CE pin of ES8316

It is 1.8V when booting linux-next kernel.


2) My board

I can't find no crack nor broken parts on my board.


2) R225, R226

As you know, RockPro64 board has no silk print so we cannot know
perfectly which resistance is R226. So this is my assumption.

PCIe, SD card slot
(top)
LAN (left)ES8316(right) USB, reset button

On the left space of ES8316 there is no resistance, only a pattern.
This is maybe R225. And 10K resistance on the right side of a
pattern. I assume this is R226.

If my assumption is correctly, board implementation and schematics
are different.

schematics of v2.1 gets something wrong...??

Thank you for reporting.

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)

I have these enabled, card is present in /proc/asound/cards, but
alsamixer doesn't work with it.

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

I'm running 5.4.0-rc6 (commit
00aff6836241ae5654895dcea10e6d4fc5878ca6) with your patch "arm64: dts:
rockchip: add analog audio nodes on rk3399-rockpro64" on top of it.

Yet alsamixer doesn't work for me. It terminates with 'cannot load
mixer controls: No such device or address'. Strace shows that fails
here:

openat(AT_FDCWD, "/dev/snd/controlC0", O_RDWR|O_CLOEXEC) = 3
fcntl(3, F_SETFD, FD_CLOEXEC) = 0
ioctl(3, SNDRV_CTL_IOCTL_PVERSION, 0xfffffd3ad04c) = 0
fcntl(3, F_GETFL) = 0x20002 (flags O_RDWR|O_LARGEFILE)
fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK|O_LARGEFILE) = 0
ioctl(3, SNDRV_CTL_IOCTL_ELEM_LIST, 0xfffffd3ad228) = 0
ioctl(3, SNDRV_CTL_IOCTL_ELEM_LIST, 0xfffffd3ad228) = 0
ioctl(3, SNDRV_CTL_IOCTL_ELEM_INFO, 0xfffffd3ace38) = 0
ioctl(3, SNDRV_CTL_IOCTL_ELEM_READ, 0xfffffd3ac160) = -1 ENXIO (No
such device or address)

Looks like it fails to talk to the codec?

mpg123 thinks that it's playing audio, but my headphones connected to
3.5mm output are silent.

Vasily
