Hi, Thenatefisher, I have test it with my R820T tunner. But the audio output is just strong digital noise , not the white noise. I think there might have issue with the USB data or in the FM demod function. How about the demod audio in your side? Would you please give me more advice?

Best Regards & Happy New Year，

Hi, Nate Fisher， Your project is great. Running the RTLSDR on the F7 is amazing. Thanks for your efforts!

Best Regards,

I'm wondering what the status is of this project? It sounds like 'szjdb' may have had issues with the audio out but fixed those? It's unclear to me. I have a STM32F746G-DISCO board and a NUCLEO-F767ZI that I'd like to try porting it to if it's working or mostly so. Just want to know before I start building tools. Oh, and I assume that to accommodate the high current draw from the RTL-SDR stick, this method must be implemented (at: https://github.com/vpecanins/stm32f7-rtlsdr ). Yes? Thanks a bunch!

Hi, nt7u, It almost work. I just remember it is not support changing freqency in runtime and lack of synchronization between the usb and codec audio stream.

Good luck! James
