[SOLVED] audio i2s with OpenElec

Giachi

this is a screenshot from ssh connection: before I used comand dmesg (the last 3 rows are about my comands modprobe)

hm... are you sure that your fex changes are taken into account? After every fex change, you have to ...

"loaded modules can be checked with "lsmod" and correct script.bin settings with for example "read_fex pcm0 daudio_used""

I mounted microSD on my pc, but inside i can dind only this files:

1. giachi@X451MA:/media/giachi/2BA2-A99A$ dir
   
2. boot.scr    KERNEL    opilite.fex  opipc_armbian.fex  opiplus.fex
   
3. bpim2p.fex  opi2.fex  opione.fex   opipc.fex              SYSTEM
   

Copy code

where is script.bin?
So the opipc.fex file in this directory is not a text file, but a bin file

Giachi

I installed in my pc sunxi-tools, then i convert the binary file opipc.fex found in the microSD with the comand bin2fex: this file has inside this:

Copy code

like the original setup without my changes

I'm not sure if I understand you correctly. You are saying that you are using your own builds from latest git sources, right? Then you are not using clean SD card. If you did, then there would be only one fex file, named script.bin. There was also one problem with update file, which didn't update fex file correctly. But it is solved. So to be completely sure that you are using latest source, please do

1. git pull

Copy code

and then rebuild the image. If you want, you can also edit projects/H3/linux/linux.arm.conf and change lines 2050 and 2051 to be:

1. CONFIG_SND_SUNXI_SOC_DAUDIO0_INTERFACE=y
   
2. CONFIG_SND_SUNXI_SOC_DAUDIO0_PUBLIC_MACHINE=y

Copy code

That way you will have I2S drivers built in and you won't have to do any modprobing.

Giachi

thanks.
For be sure i delated all OpenELEC-OPi2 folder, then:

1) Download the project with

1. git clone -b openelec-7.0 --depth 1 https://github.com/jernejsk/OpenELEC-OPi2

Copy code

2)  went inside the new folder:

1. cd OpenELEC-OPi2

Copy code

3) run

1. git pull

Copy code

it replied

1. Already up-to-date

Copy code

4) changed the file OpenELEC-OPi2/projects/H3/sys_config/opipc.fex

1. [hdmi_cec]
   
2. hdmi_cec_used = 0

Copy code

1. [pcm0]
   
2. daudio_used = 1

Copy code

1. [w1_para]
   
2. w1_used = 0

Copy code

5) changed in OpenELEC-OPi2/projects/H3/linux/linux.arm.conf

1. CONFIG_SND_SUNXI_SOC_DAUDIO0_INTERFACE=y
   
2. CONFIG_SND_SUNXI_SOC_DAUDIO0_PUBLIC_MACHINE=y

Copy code

6) comiple with

1. PROJECT=H3 SYSTEM=opipc ARCH=arm make image

Copy code

now i am waiting because is necessary a lot of time for the download  of the need software for compile;
tomorow i will try the new image.
For now thanks

Giachi

Hi, i resolved. The problem was the sequence I loaded the module, but I understood only today.

- I wrote on microSD the last image (OpenElec 2 June 2016),
- indide microSD I converted with bin2fex script.bin to fex file
- i changed
[pcm0]
daudio_used = 1


;i2s_din = portA21<2><1><default><default>    (PA21 is used: hdmi_cec_pin = port:PA21<0><0><default><default>)

[w1_para]
w1_used = 0



- then i convert fex file to a new script.bin
- I run micrSD on Orange PI PC, then i connected with Putty
- i load some audio modules with the sequence showed in the next pic (now is possible to see "CARD 1 snddaudio"):


- i changed audio setup on openelec

Thanks for your help!

jernej

Glad to hear it.

Unoqueva

Then you just have to modify the file script.bin only, or you have to recompile everything from 0.

Good work of the two.

Giachi

Today I only change the file script.bin frome the last build image
Last daus i trought to recompile OpenElec with the change in the file  OpenELEC-OPi2/projects/H3/linux/linux.arm.con
CONFIG_SND_SUNXI_SOC_DAUDIO0_INTERFACE=y
CONFIG_SND_SUNXI_SOC_DAUDIO0_PUBLIC_MACHINE=y
but my images never run; probabily because i used the  parameter
[hdmi_cec]
hdmi_cec_used = 0
(the green led switched on, but i didn0t see nothin on the screen.

Now i must understand how to autoload snddaudio modules, but i think is easy

jernej

Just make an autostart.sh script http://wiki.openelec.tv/index.php/Autostart.sh
