Hi MArco,
thanks a lot. I tested with your latest r2 release from March 2017.
However there's the same behaviour with the 768Khz file. It does not
Play. I fully agree for now it's not necesarry as there is simply no
music on the market but for testing purpose interesting that it does not
play.
Moreover I found out something additional and a difference in your and
Ralphs version.
Your's is the only one that can Play DSD512. It lloks like:
Code:

--------------------
If i use a self compiled version from Ralphy (v1.9.0-1112) with native
DSD Support (compiled with: OPTS="-DDSD -DRESAMPLE -DVISEXPORT") then
DSD works but only up to DSD256
With the DSD512 i only receive:

[13:07:47.757747] alsa_open:530 unable to set hw params: Invalid argument
--------------------
So there must be a difference in your DSD implementation right?
Thanks S
