Hello
I am using the sound design for the first time with the STM32F407G-DISC1 board.
It was set and used as manual and video.
As a result, the sound came out as I designed it.
However, after 10 minutes, it sounds strange like link video.
I think the sound is regular, and I think it is a restriction or warning on the device itself.
What is the solution or cause?

Hi,
The beeping noise that you are hearing is the timeout on the demo version of our proprietary ASRC (Asynchronous Sample Rate Converter) included in the v1.2 BSP. The ASRC is used on the USB audio stream to account for the drift between the USB clock and the CODEC clock, which causes audio artifacts if not accommodated. The timeout on the STM32F407 board is 10 minutes by default, but the timeout will increase to 20 minutes if you re-build the project without the ENABLE_MIC compiler option.
Thanks, let us know if you have more questions.
