STM32F4 I2S2 pin AF Multiplexer issue(s)?

Hi all,

when configuring I2S2 on Pins PB14/PB15 (SDext/SD)  I encounter that no data is ever output on those pins.
When configuring PC2/PC3 as SD/SDext for I2S2 the data is output on that pins (but not on PB14/PB15). WS and CLK are configured on Pins PB9 and PD3.
The chip used is a STM32F427VGT6 (LQFP100) revision Y.

Can anyone confirm that issue? Within the errata or data sheet I couldn't find anything in regard to this.

Additionally: Does anyone use I2S and an ULPI phy on a design?

Thanks in advance,
bs
