Hi Folks-
I'm using Audio Weaver Designer with the STM32F746 Discovery board. I was able to follow the directions in the STM32 F7xx Discovery Board
Setup Guide (page 9) in minutes to get audio output on the headphone jack. However, the line-in wiring configuration (3rd and 4th outputs of SYS_deinit outputs wired to the two SYS_inter inputs) is not working. The line-out output is silent when a stereo signal is presented to the line-in jack. Does anybody know how to correct that problem?
I'm using Audio Weaver Designer Version 6.18.02 STMicro. I'm using the STM32F746_Discovery_SW4STM32.bin BSP.
Incidentally, for other newbies like me, you'll need to wire the unused outputs of SYS_deinit to Null Sinks. That wasn't in the setup guide. Hopefully it'll save the next guy some time.
Thanks - John Speth

I'm the OP. I have fixed it but there is something wrong which I'll report:
The basis of my failure declaration is through the use of AudioCheck.awd which I found in "$\DSP Concepts\AWE BSP stm32f746 s1.4\STM32F746_Discovery\Examples". Line-in is silent when I use that project. Line-in works correctly when I wire up the same circuit after starting a new project. Why that difference is significant is unknown to me. Would anyone like to speculate?

I'm the OP again. I retested my assertions I made in my previous post. Line-in does indeed work with AudioCheck.awd. I must have had some persistent newbie confusion. I suspect my line source was not adequate. Sorry for my noise.
