Still couldn't get his DAC to work, but at least the proof of concept code works with the XDuoo XD-05.
Once JD1's DAC is working, I'd release the kernel, and the source (to make it GPL compliant).
Until then, if you have a native DSD capable DAC, and want to join the test, please generate a diagnostic file and send it to my email address: agent_kith 'at' snakeoil-os.net (Replace 'at' with @).
Benefits of native DSD?
- Potentially resolve POP noises some DACs have (as it's no longer DSD wrapped in PCM format)
- Potentially less overhead (sent as true bitstream)
- Probably will support DSD256 and DSD512 as it's no longer constrained by PCM bit rates
- Potentially will make you feel the AQ is better because it's native DSD.
