STM32F7 HS USB Audio Issue

[fft]

I browsed the forum it looks like people already asked this question but no clear answer has been posted.

Like others, I am able to run the USB FS Audio example on Disco board (746) but it gets into 'Incomplete ISO Interrupt' error on HS mode.

I recall at somewhere it says HS Audio is not supported. I'd like to know if it's a software issue that can be solved in the future or a hardware one?

'Cuz at this moment I need to decide whether to work around this by using a 3rd party I2s to USB bridge chip on my schematic -- if STM is really that bad,

or it CAN be worked out and save me some production cost.
