Suggestion for an "open source" DAC

Hi,

I am in the market for an Open Source DAC. And I’ve been told that Khadas Tone is a great choice, but I can’t seem to find source code for firmware.

  1. Could you point me in the right direction?
  2. Is the source code available for Tone 2 Pro? or Tone 2?
  3. Which parts of stack are made open source? Can I for example write my own audio filter?

Thanks,
Tyler

Is there any update on Khadas “Open Source” Tone2?

Thanks,

Yep, WIP, but slightly delayed :stuck_out_tongue_winking_eye:

Thanks, looking forward to it very much :slight_smile:

Is there any update? I recall there was some mention of releasing the source for the Tone1 all the way back in 2019?

Would love an update
Looking forward to seeing the OS Tone!

In fact, you can find es9038q2m program control in GitHub and USB Audio 2.0 program on XMOS website. However, both T1 and T2P are closed-loop control, and you can’t use external control.
