Jean-Charles,
Most of the output problems seem to occur on UAC/UAC2 output protocols
that require bit true outputs. These include MQA and DoP(DSD over PCM).
both of these protocols seem to fail to work correctly. Both of these
protocols embed a flag system in the samples to work correctly. Since
both of these work on all the other IOS devices, something must be
effecting the samples on the USB-C version that does not happen on the
Lightning versions.
I bought an iPad Pro 12.9 over the weekend (should be here by WED) and
will do some tests and create another bug report.
I forwarded your bug# to my contacts at Apple.
Thanks,
Gordon

Hi Gordon,
As you probably remember, our devices mainly use the input (recording) so I
could not dig too much around the « output ».
Last week, I quickly tested the red Dragonfly DAC and could not « hear » any
problem but of course it does not mean that everything is ok.
Thanks,
JC
