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
