This looks like the most detail I can find. The guys at Elk say it's possible, as long as the audio driver exists.

The OS itself being for musicians seems better suited to the Audio Injector stuff than it is to the HiFiBerry.

Any information anywhere on the Elk Audio OS - what hardware, kernel, etc etc ?

It's the same ADC and DAC chip as the HiFiBerry from what I can tell. So should be pretty straight forward right?


They use different audio codecs. It will take some work.

I'm sure hoping that someone responds with a "yes", but I have a feeling it's currently, "not yet".

Here's a thread from a little over a year ago:

The existing ALSA based AudioInjector driver won't work with Elk.  Someone would have to explicitly create a real-time audio driver (again I'm hoping, but not finding).

The ray of sunshine might be that ELK did it for HifiBerry:

AudioInjector could probably help their sales if they created an ELK driver for us.  Hint, hint.

Hey Michael,

Do you know if Elk Audio OS will be compatible with any of your ADC ADC products?

Cheers,
Chris
