RPi-DAC is now Durio Sound

I have a case for 8 batteries too witch gives more or less 9 volts.
I m testing that option too. Mine are 2000 mah i think. Now i want to try a linear supply too see what happens.

Using the Raspberry clock is not ideal is it?

No it“s not but this is not not a big issue with circuits that use PLL. Most if not all circuits used in modern designs have PLL which give a clean and stable clock.

Sorry audiotweak I have made a big mistake telling you that the clock is from Raspberry. :unamused:

Thank you Stephane! You are right!

In fact this is taken from Durio Sound web site:

ā€œThe DAC PCM5102 runs in PLL mode, no SCLK signal needed (which is not provided by the RPi).ā€

Thank you and thank you again.

Just ordered a dual mono and wonder when it comes in do I just burn the Volumio 1.55 on the card and then it will work? The unit comes with its own flash card with an operating system but I don’t know if it needs the Volumio image to run with Volumio.

thanks for your help.

Hi Guys,

I am a noob and new to this. I have recently purchased and received the Pro+Basic boards, and am wondering how do I setup for Dual Mono output?

Wesley - how long after you ordered the board did it ship?

It took about 2 weeks to arrive from the USA to Malaysia.

Btw, can anyone help to enlighten me on the dual mono setup? Thanks.

I’ll be looking into it when mine arrives - maybe I an offer some help

Thanks!

I’ve received my DurioPro and tested it with Volumio 1.55 and RPIB+. Everything works well.
In this video, the power source is a HTC charge (5v-1A). Last week, I’ve tested the system with a 12v battery and It sound much better :smiley:

Powering Durio by raspberry 5v micro usb you don’t use lmz14202h, increase the quality using mini jack female and 12v battery is normal. What is strange is that lmz14202h is a switching chip 12v battery or 12v switching wall plug should be the same.
But some of us has told that battery is better and It’s strange.
What is the capacity of your battery? How many hours of use?

My battery’s capacity is 12Ah. I’ve used it for 4-5 hours and the voltmeter indicated 12,25 V (when the batery is full, it indicate 12,56 V). In the manual of the battey, the working range is from 10,5 V to 12,5 V.

Thank you for answer!
You have choose a battery with a good capacity, bigger is impossible at home! 3,5kg lead?! :wink:
Raspberry and Durio should absorb 1.5-2A max (I suppose, no measure) and 4-5 hours of working is the time I expect.
I think that battery isn’t a good solution, not very convenient charge it at home every 2-3 times you listen music and you must choose e sealed one to avoid poisonous gas during charge.
As I have already written use a DC switching wall plug 9V or 12V should be the same, because lmz14202h is a switching chip and has the same interference of wall plug.
I’m using a 12V DC wall plug and I have no battery to make a comparison, if someone can do it should be intersting… :unamused:

Wesley,

Do you have more than one flash card? The first thing I can think to do (once I get my unit - the order hasn’t been processed yet and emails have gone unanswered :open_mouth: ) is to burn a clean image of volumio 1.55 and see if that works. I say that because I’m told that the unit comes with a flash card with image of something already installed and I don’t want to overwrite that in case I need it back.

I’ve asked the same question and hope someone can chime in and help us.

Hi George,

Personally I don’t quite prefer Volumio although I have tried it. I preferred another image running on Archlinux (one of the two) and it’s working well now.

My only question is how do I wire the Durio boards for Dual Mono. I have a Pro and 2pcs of Basic boards at the moment and am seriously thinking of adding 3 more if this (dual mono) is proven to work better.

Thanks for your kind assistance, George.

Well the board I ordered comes pre- assembled. When and if it ever comes I can take a look and see if I can help you figure it out.

What I’m not familiar with the image you are working with - could you point me to the source?

Thanks,

George

Hi George, I’m using Archphile.
