DAC converter connection with Raspberry Pi and audio port of laptop

Hi, I have small speaker which is connected with  DAC (operating on 10v DC) converter which is interface with   raspberry pi. I want to connect my laptop audio port to raspberry audio port and wanted listen laptop audio files from speaker (connected to DAC converter) But I am new to this field I need help (any reference schematic or code which will help me to make it work), your suggestion this will be very helpful   

Hi Bart-I think the simplest way to do that would be to get a USB sound card (under 5 bucks on eBay).  As you know, the Pi has a so-so quality audio output and no audio input. The external sound card solves those problems. You'll need to load the driver files for the sound card before it will work.  The USB sound card drivers for the Pi are easy to find on the Internet.-Rick

Bart,As Rick said, the easiest way to get audio from your laptop to a Raspberry PI is with a USB sound card.On the other hand, it sounds like you have already built a DAC and interfaced it to the PI. Presumably, you have some code that allows you to send data to the DAC from the PI so all you need is to get the audio data from your laptop.My first approach at this would be to  copy a WAV file from the laptop to the PI and then send the data from the file to the DAC.
WAV file format is easy to find and decode. it is likely that there is some code for the PI to do that already.Another (much more complicated) approach would be to make software on the PI that would emulate a USB sound card to get the laptop to send the audio data. I'm sure there's an easier way than that though.Good luck with your project and let us know how it turns out.

Is it possible to use I2C based DAC controller interface with raspberry pi for listening audio files from laptop windows media player without special software or app for that ?

I just came across this offer from Elektor:High-End Audio DAC for Raspberry Pi.
Perhaps this is what you want...

You could do it if you had the PI emulate a USB audio device (like USB speakers). Another possibility is if your PI has an audio input jack you could send the audio through an audio jumper cable to the PI.In either case, you will need software for the PI to receive the data and send it to the DAC.
I suspect there is another way but I don't really know enough about the PI to say what it is. I only just got one and haven't even had a chance to get it out of the box.

Hey check out the product i have search out from NCD.IO this DAC will resolve your query
