OrangePi 4 LTS microphone issue

[Mr. Fennec]

Hi, I installed recent server armbian on orangepi pc 4 and trying to make the microphone work

The command I use 

 

arecord -D hw:0,0 -f cd -d 5 test.wav

 

The setup

root@orangepi4-lts:~# uname -a

What could be the issue?

I tried to change alsamixer levels, but it didn't help. I still hear just some white noise when listen to test.wav

Any ideas ?

Hi ,

 

some issues her too with my OPI 4 LTS. 

can you show me the output of

aplay -L

 

and start recording, give me the output of

cd /sys/kernel/debug/clk

cat clk_summary  | head -3 && cat clk_summary  | grep i2s
 

I interested to compare to my  linux kernel 6.12.11

 

Thanks

Hi,

I got my recording from Headphone Mic fixed.
 

Here is what I make work for me:

a)

have pinctrl-0..2 set in the i2s0

b)

make sure the reg=0x11 for the i2c1-codec

c)

add the Mic Bias.

 

Tested with 6.12.12 which got a fix es8316 codec.

 

&i2s0 {                 
        status = "okay";
        pinctrl-names = "mclk", "bclk_on", "bclk_off";
        pinctrl-0 = <&i2s_8ch_mclk>;

@Christopher Ruehl thanks for looking into this issue, I will incorporate the fixes into mainline armbian as soon as possible!

Hi @jock,

 

If people like to use the onboard Microphone of the OPI 4 LTS, need to change MIC1 -> MIC2:

simple-audio-card,routing =
                        "Mic Jack", "Mic Bias",
                        "MIC2", "Mic Jack",
                        "Headphones", "HPOL",
                        "Headphones", "HPOR";
