The STM32 seems to be a nightmare... Just such weird issues constantly. Anyways, I'm trying to output Master I2S (with BCLK, no MCLK) at 16 kHz, but for some reason am getting a 1.027 MHz clock causing audio artifacts. Input clock is PLL2 or PLL3, doesn't make a difference at 2.048 MHz or 20.48 MHz, doesn't make a difference...

Any ideas?
