The Orange Pi series of boards are extremely low cost alternatives to the Raspberry Pi.
You can get an Orange Pi One delivered for ~12€.
They are open source hardware & software.
They do not have as much community support as the RPi but the do work. My issue is most likely a software issue.
I need to investigate further but I'm not in a hurry since I am using mine for streaming music to my kitchen's stereo (not-quite-the-hi-end setup).

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.
I did some testing. It turns out that everything works fine as long as I force output at either 16 or 32bits.
I read that MPD's default MP3 decoder always outputs 24bits so that might be the problem.
So a setting of format "*:32:*" works fine and should not be doing much damage to the music.
I'm not sure though whether it's a problem with the Orange Pi or the 9023..
My 2 cents the orangepi I2S driver does not handle correctly the alsa 24bit format and outputs the samples shifted by 8 bits downward, attenuated thus by 48dB.
That sounds about right.. I'm testing my setup with an AVR and I have to turn the volume up to above 0db to get the volume that I should be getting at about -40db. I'll try contacting the devs of the distro I'm using (armbian).

Opi PC speaker Test Command nötig found
Hello everybody,
I'm new to the topic and bought the opi pc and teradak es9023.
I have Download the image of jassie and connect the pins as Show in the picture.
I Boot the opi PC and try to use speaker-test but it comes command not found.

Please can someone help me?
Thanks.

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 andgives me pink noise on both channels....Code:sudo speaker-test -D hw:1 -c 2
It would have been nice to have HDMI with all Channels and no downmix to 2 but anyway:
Thanks for this great work ua3nbw !

Hi, i connect the TeraDak an use the two pin connector like the Color, but the Color is nötig Right in my case, Black is +5V and red is GND.Hello,
i have a Orange PI PC board with Allwinner H3 chip and i'd like to connect a i2s DAC (Teradac with Sabre ES9023).
![]()
At page 62 of H3 datasheet is writen:
Compliant with standard Inter-IC sound(I2S) bus specification
Compliant with left-justified, right-justified, PCM mode, and TDM(Time Division Multiplexing) format
Full-duplex synchronous work mode
Mater and slave mode configured
Adjustable audio sample resolution from 8-bit to 32-bit
Sample rate from 8KHz to 192KHz
and page 79 shows i2s connection:
PCM0_BCLK = I2S/PCM Sample Rate Clock/Sync - I/O
PCM0_BCLK = I2S/PCM Sample Rate Clock - I/O
PCM0_DOUT =I2S/PCM Serial Data Output - O
PCM0_DIN = I2S/PCM Serial Data Input - I
but i don't understand if PCM0_BCLK is LRCLK (WS) signal or no.
Someone can help me?
Do you know that the TeraDak has a polarity Protection?
Or is the dac defect if you connect this with wrong polarity?
Regards
A friend of mine came over a few days back with one such DAC that wasn't working. I noticed that when I was powering it up, it was shorting my power supply.
I took a closer look and saw that it had the red and black wires put in the wrong way. The power cable that came with the DAC was faulty.
The end result was 2 blown LDOs on the board.
I suggest that you fix the cable before you power the thing up.
If you've already given it power, chances are that your LDOs are gone. Hook it up the proper way (according to the marking on the PCB) and check for 3.3V on the LDO's outputs (just probe all pins, one of them should be at 3.3V). If you measure just ~1V then the LDO is gone. Ask for a refund.

Hi Dimdim,
Thanks for your answer.
But i have already tried and found only after it Support hat the cables are wrong and then replaced immediately.
which components you mean LDO, I can measure it and replace?

How can i Test this?

Measurement of LDO
Hi,
I found on the net a data sheet and have between measured pin 5 and pin 2 3.2V and between pin 5 and pin 1 5V, if I have understood correctly then the LDO is still working.
Please See the picture.
I there anything else which can be damaged?
Thanks in advance!

If both LDOs check out fine then your DAC is probably OK.
You say that you don't have speaker-test. Are you running Armbian?

I installed Jessie as discribe here.

I have measured both f the LDOs, on both sides i find 3,2V, i think my power suply was not strong enough to damaged the LDOs only 1A.

I tend to use whatever works best for me.. 🙂
Armbian is widely regarded as problem-free for the Orange Pi boards.
If you try to use it, you'll probably have to do some light editing of the FEX file to enable I2S output.

Just the LDOs for now - I'll resume testing once the replacement parts are in.
Normally I wouldn't have bothered fixing this board (it is after all dirt cheap), but since the LDOs were ~0.20€ I thought I would spend the 5 minutes swapping them in.
Plus it's a pretty cute little board - I couldn't just throw it away.
Just a quick question, has anyone tried to do a 'capture' with orangepi by putting an I2S ADC at something higher than 16bit, eg 24bits or 32bits?

Hi friends
I'm new I have Dac PCM5102 DAC Decoder Player I2S it and connect as shown in the first page but with home cinema amplifier it works well and when I plug the speaker sounds almost not hear.
they must add amplifiers dac has this card or not, normally that with thank you pregnant
