Is it possible to know the instantaneous data/sample that has been sent by the I2S DMA transfer

Hello.

I have a successfully configured the I2S peripheral that continously sends (with the desired frequencies) a vector of data to an external DAC. The transmission is done with the HAL_I2S_Transmit_DMA function.

Since the transmission is done in the background, i don't really know, if it is possible to monitor (or know) the instantaneous data/sample (e.g. the 64 bit (L and R) data, or 32bit (L or R)) that has been sent with the I2S? I mean on a register which can be read every time the new instantaneous data has been sent. 

Thanks for the feedback in advance.
Best regards.
