Wolfson and MPD  working

superpat

Hi,

 

I installed MPD onto the provided Wolfson Audio distribution, running it headless,  console via ssh.

 

I copied the provided demo flac files to the mpd music directory.

 

I ran alsamixer and wound up the digital i/p's and outputs.

 

controlling  MPD with the GMPC client on my LInux desktop

 

96Kbps flacs are playing  superbly, output  lineout  and into my desktop audio amp and speakers,

 

Next I will set mpd to get music from my NAS using nfs, which will be interesting, as this tends load the Pi system and  cause problems with the Pi and usb dacs!

 

cheers

  • Hi,

     

    I'm excited to see that someone actually has the wolfson audio card and got it working with MPD! I'm currently using a USB dac and the pops and clicks are driving me nuts.

    So far have you noticed any audio glitches? What's your opinion of the p5 head sprung connector? Does it make a solid contact? I was considering the hifiberry, but the soldering kind of turned me off. I wonder if the sound quality will be comparable.

     

    Thank you!

    The Hifiberry appears to use the same IC that I've tried on a BeagleBone Black, it is a very high quality part (used in $300 Meridian USB sound cards), but it looks like the hifiberry does not have an on-board oscillator which is needed for good audio quality. I could be wrong. Just going by the photo here about a third down the page. I don't see an oscillator but perhaps it is on the rear of the board.

    The Wolfson board is lower cost (and more functionality - including digital out) and it would make sense to go with that one I think. But I don't have experience with it.

    From a hardware point of view it won't have effects like skip or anything like the USB ones you've experienced. The interface is very different, and is at a determined rate with no contention from other devices like USB. It is a dedicated audio interface.

    Shabaz, thanks for the reply. I wonder what I'll do with my pifacecad after I get the wolfson card. I wonder why wolfson recommends not using a usb hub when using the card? Power?
