RPi-DAC is now Durio Sound

[badger]

Fantastic job!
Let me understand your creation!

1. Durio Dual Mono
2. RPi b+
3. Case and power switch
4. HD SSD connected to RPi.
   All seem powered by a power bank using RPi micro usb port.

Why don’t you use the power switch and an AC 6V transformer or a DC 9-12V directly to Durio board?
Why HDMI connection? And what’s the blue USB cable?

[wesleywong]

1. Durio Dual mono plus additional two Basic boards.

2. RPi 2

3. Yes it can either be powered by a 9-12V/2A AC DC adaptor or 5V/2. 1A powerbank for clean DC power

4. I connect the HDMI to a 7" TFT IPS LCD as console so that I don’t need to rely on Wi-Fi for GUI. I use ncmpc.

5. Lastly the blue USB 3.0 connects the Pi2 to my iFi iDSD Micro to play DSD audio.

Hey duriosound users,

I have the dual mono board and I’m interested in adding a spdif output. Anyone have experience with this?

[StefanoLa]

Can anybody explain me about the this problem? What is asked exactly? Can anybody explain me about device?

@StefanoLa

The device is called Durio Sound, a DAC that connects to a Raspberry Pi using the I2C interface: duriosound.org/.

There are several models available: Check out here: gravitech.us/dusoulsoqufo.html

The products are a development of Torsten J, an audiophile electrical engineer: tjaekel.com/T-DAC/

I bought a durio sound pro (gravitech.us/duriosoundpro.html) that I am running with a Raspberry Pi B+ (using an external power supply that also powers my PI. I am amazed by the sound! Fantastic product - incredibly good for the costs!

[badger]

Is it possible to add Durio Sound Pro to the list of I2S DAC?
Now I’m using hifiberry driver, but should be better use the settings below:

Hi guys!
I have found a player that full support Durio Sound PRO: moodeaudio.org/
Look to the RELEASE NOTES it seems very good player, Linux Kernel and MPD always update!!!
moodeaudio.org/docs/tcmods-relnotes.txt

I’m going to test it! :mrgreen:

[florianh]

What’s wrong with using the hifiberry driver for durio pro?

@florianh

I’m not software expert, but use is right driver for me should be better.
For example, Yesterday I listen with Volumio some tracks and the sound not convinced me 100%.
Now I’m listening same tracks with moode audio setting Durio Sound Pro driver, also DAC chip name is recognised, and seems to me sound better…
If someone can make a test and confirm my impressions should be a good thing.
For me is really better, more details and clarity! But should be only a stupid illusion in my head.
Can you try to test it?

It is! :mrgreen:

1. The driver module is clearly a copy of Florian Meier’s HifiBerry DAC driver, with a few strings changed. It adds nothing new, and actually omits the logic to locate the I2S driver using Device Tree. I am reluctant to merge a clone just to change a few strings. Perhaps what is needed is to remove the strings from the other driver, or to allow them to be extracted from Device Tree.

2. Going forward we won’t be accepting patches to the board support code adding some platform devices - that is what DT was created for.

3. The overlay looks fine, but then it should since it is a copy of the one I wrote for the HifiBerry.

@pitichai commented on Mar 3

Hi Pelwell,
Thank you for your comments. To be honest, I totally accept that I rewrite the code which is written by Florian Meier for RPI-DAC (rpi-dac.c) not for Hifiberry DAC. Due to this Durio Sound DAC is designed base on RPI-DAC (Me and Torsten), but RPI-DAC is using pcm1794a dac chip and durio sound is using pcm5102a. With pcm5102a codec will allow me to play pcm up 32bit and 192kbps song. And Hifiberry DAC is using pcm5102a. I do understand to not accept the patch due to the code look pretty like coping and just change the string name.

For Hifiberry DAC (HW) is available for RPI A and B, and for RPI B+ and RPI2 B will need to go for Hifiberry DAC+. For me I am happy to close the PR, and I can offer the module driver to Durio Sound users on my community support forum, if they want it. I also told them that Hifiberry DAC is working, but on the previous kernel 3.12.y. Some users said durio sound driver provide sound a bit bigger than Hifiberry DAC driver.

Secondly, Yes for overlay file I follow the one you wrote for hifiberry. Due to it use i2s port and same dac chip. I just think to use durio name configured in /boot/config.txt will be easier for users.

Thank you very much,
Pitichai

[badger]

Thanks penots!
But if I have read well Pelwell doesn’t want to add Durio Sound driver because for him is a copy of hifiberry driver.
Otherwise Pitichai has told that the DAC is the same, but he has rewrite not copy the code.
He understands that Pewell doesn’t accept the patch, because the code look pretty like coping and just the string name, but this isn’t true.
He followed hifiberry driver only because it has i2s port and same chip.

Thanks for clarification!

Thanks for clarification!

Or maybe the moode sounds better…

Now we are sure that Durio Sound Pro sounds better with Moode because uses is correct driver.
The differences between Volumio and Moode are that Moode uses last debian kernel (jessie) and one of the last MPD.
Volumio is not update…

[florianh]

Does anyone know if the upcoming Volumio 2 will ship the correct driver for DurioSound?

Moode sounds outstanding in my system. I compared with volumio 2.0 in focus mode that is very near but moode is better , i m using sabre dac.

I don’t know MPD version of Volumio 2.0, Moode has version 0.19.10, one of the last.
There is a guide in this forum to update Volumio to the last MPD, I tried with Volumio 1.55 without success.
I don’t know if this could be one of the reason of this difference.
I don’t remember if SABRE DAC is in the Volumio i2s DAC list, if not, use the correct driver with Moode, like in my case, make the difference.

[acousticmood]

I bought a dual mono pro a while back and love it. Unfortunately I corrupted the card and re-flashed. It works but there is no sound. Are there any special configurations I need to add to the 1.55 version? I thought a copied the original when I got it but I can’t find it - please help.

Thankyou,

George

[badger]

For Volumio 1.55 you have only to select hifiberry and reboot. I suggest you to download and install Moode Audio, better than Volumio for our DAC.
You can choose Durio Sound to the list of i2S DAC and it works better because it uses his own driver. Graphics is very similar to Volumio, is a software developed from Volumio.

[acousticmood]

Thankyou Badger - I will give it a try
