PIANO HI-FI DAC / Re: No audio
« Last post by sparkyadmin on July 28, 2017, 02:56:54 AM »

   If you want the on-board Raspberry Pi sound devices to be enabled then  we need to change dtparam=audio=on.

LED of piano DAC is glowing?

Please download volumio image from below link for RPI

And flash the image then enable I2S DAC and select output device and DAC model as Allo Piano and check.

   dtparam=audio=on should be on only.

After booting volumio image you have to select Output device as Allo piano dac and I2S dac should be on.

Please find below link for your reference.And try to play the song

Note:Then also not working means download fresh volumio image and flash the image to sd card and check.Select audio out put device as allo-piano dac in volumio gui and enable I2S as shown in above link.

"Add below line in config.txt file" and
"And make dtparam=audio=on "

   It will not provide audible difference.It will provide proper voltage output ripple.

Looking at the available power supplies on Allo web site, RPI/Dac can be powered from 5V supply and volt/volt+ from 19V supply (plus CM for Volt). Do you expect that the DUAL LLC PSU option will provide audible difference? 

     You have to connect 3mm jack(21v) to volt amp and 2.5 mm jack (5) to kali board.

   Add below line in config.txt file


And make dtparam=audio=on

then Reboot and check the status.

Please check the driver is loaded or not using "aplay -l"

I purchased the Vana Light 2.1 and the Dual PSU and the Volt Amp Plus with Stepped Attenuator. It was quickly delivered on July 3.The PSU will power the Volt Amp but will not power the Kali, Sparky, Piano 2.1. I was excited to hear how good it sounds but my frustration is winning over. Has anyone else had this problem and how did they fix it?

Hallo, I've just received your DAC; I've connected it to a Rapberry, set up Volumio: I2S DAC, Allo Piano. When I try to play a file, it gives the error:
Failed to open Alsa; failed to openAlsa device "hw:1,0: no such file o directory

I've another Raspberry with another DAC well working.
What can I do?
Thanks, Enzo
