BigSur doesn't recognize Thunderbolt Display Audio, USB, Mic, Camara

Hi there.

I just update my iMac to BigSur ...

And when I connect the Thunderbolt Display, the only output sound is Internal display (iMAC) , and the Thunderbolt Display audio out don't appear in the option as the OS Catalina did. Also the MIC, Camera, USB. The image works great, but all the other stuff don't.

Someone can't tell me how I can work around this issue?

Thanks in advance.

Ok, I reset PRAM and unplug both iMac and the TBD, and works.

Its appears to be that the issue.
