Wolfson Pi Audio Card

MichaelL65
MichaelL65 over 12 years ago

This looks like a really good addition to the RPi. Just a few questions:

 

1. When will it be available?

2. What will it cost?

3. When will we get a technical data sheet?

 

I may be able to make it into a guitar pedal board now...

    Hi there,

     

    plan is to have the boards in stock and have a "full" launch with all the documentation etc on 20th November.

     

    Price is still TBD but will be around $30.

    Hi,

     

    I would just like some basic performance  information, so I can decide whether to buy this DAC or another manufacturer's product

     

    Can it  play 192Khz x 24 bit files?  if not what?

     

    What's the noise figure?

     

    any other gems appreciated.

     

    thanks

     

    Patrick

    Hi Patrick,

     

    the Audio Hub is the WM5102. We've loaded the product brief and full datasheet onto the webpage for the device Audio Hubs (CODECs) | WM5102 | Wolfson Microelectronics

     

    Yes it can play 24bit 192Khz files.

     

    Cheers.

    Hi Michael,

     

    After a minor glitch with the hardware we've now got boards turning up at the warehouse in their thousands. Main focus now is on getting the software drivers to a level we're happy with before releasing. We're working closely with the Raspbian team as well as the team at Element14 and we'll keep you posted as soon as we have a firmer date.

    WM5102 seems to support TDM, so is it possible to output multiple channels of audio using this audio card?

    You know RPi PCM interface doesn't as such support TDM but its very easy to make the frame sync signal from the LRCK signal for TDM.
