Thank you so much ua3nbw !!!.
 
Wow! It works. Second try, I extracted the kernel from ua3nbw ,everthing that is in "boot" and the folders firmware and modules (to be found in lib) and copied them to the sd card with Jacers Img. Then I connected the card as shown in #21 and
Code:
sudo speaker-test  -D hw:1 -c 2
gives me pink noise on both channels....
It would have been nice to have HDMI with all Channels and no downmix to 2 but anyway:

Thanks for this great work ua3nbw !

Regards

Awesome news !!!

So many thanks skyunlimited for your work and efford.

Regarding your question about HDMI multichannel audio I think you know that thread http://www.diyaudio.com/forums/pc-based/204512-rasberry-pi-active-crossover-revolution-13.html

There seems are the only real possibility at the moment for manage multichannel audio (hdmi) on rpi, but I think because is based on a generic linux modules updating it can be "easily adapted" to work on opi too.

Good job !

I`m still waiting my opi board from china... so tired on waiting

:cheers:

Hi all,

I have finally received my OrangePi One and installed Armbian on it.

I just had to disable twi1 in script.bin, because it uses the same gpio pins as the DAC.

[twi1]
twi_used = 0
twi_scl = port:pA18<3><default><default><default>
twi_sda = port:pA19<3><default><default><default>

and then of course
[pcm1]
daudio_used = 1

Then I connected my Sabre ES9023 as others allready identified and it works straight away!

Hope it helps!

Well! Are you working to some specific project?
 
I have here an Orange Pi One connected through I2S to an 9023-based DAC.

It is running MPD 0.19 on Jessie Server (current version).

Everything seems to be working fine when I'm playing FLAC files but when I'm playing MP3 files the volume is too low.

It doesn't matter whether I have volume control enabled or not.

The problem goes away if I force "format "44100:16:2" in my mpd.conf.

Has anyone else come across this issue?

Btw, it plays 192K/24bit material just fine..

Very likely the DAC accepts only some specifications of I2S (samplerate, bit width). When MPD does no conversion, your DAC does not handle correctly the native formats of some of your tracks. Your flacs happen to fit your DAC input params, while your MP3s don't. I would check the I2S driver/controller capabilities/setup with regard to the ES9023 specifications.
