Tried the uac2_headset example on stm32f103 and stm32f303. Same problem: |

Hi, I compiled it for Segger RTT. (clean, then make BOARD=stm32f103_bluepill LOG=2 LOGGER=rtt all) The log: |

Same happened with the stm32f303cc: |

Note, that the skuep AIOC (stm32CubeIDE project using his modified TinyUSB version) is properly working for me, and I succesfully finished a project with modding it. (without understanding, why it's working and the very similar uac2_headset sample is not) |

Stm32f303cc only have 512 bytes packet FIFO, thus can't fit the packet buffer requirements of uac_headset example. You can reduce size by looking at how |

I read in the comments of the above issue, that there is some progress. skuep wrote:"Hi guys, so I got UAC2 speaker and microphone working on an STM32F302"
Not sure, if the improvements are already merged to the current TinyUSB code, or that is a separate fork?
I am about to write isochronous transfer from host to device for an STM32F303. Just sound from a PC to the built-in ADC.
Should I start from the examples like "audio test" or "uac2_headset", or these are still not working on devices with fsdev, and better to start from skuep's working project? (unfortunately I have no F302, so can't test it in the original form)
This solution is working on other uC-s with fsdev like STM32F103 too?
