Technical Questions / problems !!!!
« Last post by keithjohngates on January 17, 2018, 04:15:21 PM »
Hello,
Hoping I can get some help.
I am trying to get Spotify broadcasted to my sparky+kali+piano2.1 to send the signal RCA to my tube amplifier.

I have tried: DietPi
I could  stream via my laptop spotify (or straight phone spotify) via the app AirSpot (on my phone): onto the Gmrender on Dietpi. So this worked but it was slow and sometimes dropped out. Also whenever I wanted to change the song I found I had to disconnect and reconnect. A pain in the arse....

Next I tried the android installation - this would be great. Got the installation working just fine. However - no sound. No way to control the audio output from the piano - does this not exist???? Are there no android drivers for the piano?????

Then I tried the ubuntu version - thought this would be the solution as you can have spotify for linux and I can see on that it includes drivers for the piano.

However there are two issues with this install - one it seems to imply from the install instructions that it has to be done on eMMC although the instructions are a little ambiguous whether it can be done on an SSD.

So I tried to install it on an SSD - the installation on the card seem to go okay - but the sparky wont recognize the os.
Wondering if this has something to do with a) the android flashing - you have to plug the sparky in via USB when flashing - does this do something to sparky that means other OS on the SSD wont be recognized???

Or does ubuntu install need to be on an eMMC??

I absolutely love the sound of the piano - I built my own speakers and valve tube amplifier and it sounds amazing....Way better than when I use the audio jack (DAC) from my phone.

Just need an easy way to get my spotify music through the sparky and out the piano RCA.

(As an aside one of my primary RCA channels failed on the piano so I have to use the subwoofer ones - which seems to be identical in performance as the primary ones)
Does anybody know what the after market service from allo is like???

Thanks for any help.

Hi,
   
    As we said earlier,In Digione  there is no left and right concept. That is SPDIF out single line.

Which converter you are using after digione?

Means SPDIF to analog converter

I use Audio research DAC7 (both of USB and SPDIF to analog converter)

Hi,

   For Digione , there is no left and right channel seperatly . That is the SPDIF out (single line protocol)  .

May be you have to check the SPDIF to Analog(left & right) converter.

Yesterday, I checked my DAC with below step:
- With USB port: Two channels were balance
- With RCA Coaxial: Left channel louder than right
- With BNC port: The same situation as Rca Coaxial

Pls give me more advise

Tks

KALI RECLOCKER / Re: RPI+ISOLATOR+KALI Connections?
« Last post by hifiman on January 09, 2018, 02:04:02 PM »
Hi,

   You need to give power supply for RPI and KALI board.No need to connect battery or power supply to the isolator board.

I already had a working raspberry pi -> Allo Kali Reclocker -> I2S DAC in slave mode

I just received my ISOLATOR , MCLK, BCLK and FCLK are there, but no i2s data signal coming out on pin 40 of the isolator.

I have isolator configured in slave mode.

Any idea on why there is no data signal?

Edit: I just figured it out, needed to place the jumper on the reclocker board in order to let the powered reclocker board feed power to the isolator.

Hi

I setup my RP2 with Digione

However, when play music the left channel louder than right

I tried with Usb connection from RP2 -> it still normal

Maybe Digione had some mistakes?

Pls give me the advise to resolve this issue

KALI RECLOCKER / Re: Maximum supply voltage?
« Last post by sparkyadmin on January 05, 2018, 04:46:10 AM »
Hi,

    We can feed only maximum 5.3 volt.

And operating voltage should be 5 volt.

KALI RECLOCKER / Maximum supply voltage?
« Last post by JosV on January 05, 2018, 04:18:36 AM »
Hi there,
what is the max input voltage that the Reclocker can handle?
I want to feed it with a 6 volts lead acid battery (agm).(pure DC ;-)
Just loaded 6.4/6.5 volts.
Thanks in advance, greets from Netherlands.
