Hello everyone,
It took a bit of time to messing around today to get this to work, so I thought I would post (details may be specific to the STM32F4 microcontroller I am using).
But I do have a question also for any STM32 experts at the end.
On the STM32 platform the if you pick a external crystal with frequency that is a multiple of the 96kHz then you can, unsurprisingly, get 0% error between desired and actual I2S frequency. 24.576MHz / 96kHz = 256, so 24.576MHz seems a good choice being a standard frequency with lots of options of low-cost crystals.
USB needs exactly...

Would you like this moved to a more appropriate forum? If so, report it and tell us where to place it.
Thank you.
Thank you.
