Slice Posted October 23, 2022 Share Posted October 23, 2022 Because you chose iMac17,1. Choose iMacPro1,1 and compare results.

Yes, you have to try all layouts rebooting everytime or you may try VoodooHDA with one attempt.

SamDaPiRatE Posted October 24, 2022 Author Share Posted October 24, 2022 Bingo!!! That's it!!! I've installed VoodooHDA, and now sound card is detected, but only in front. On HDMI nothing cames out But, now the videos don't crash anymore Thanks for your help!

Slice Posted October 24, 2022 Share Posted October 24, 2022 Yes, VoodooHDA is not working for HDMI. You have to give way for system AppleGFXHDA.kext as I did.
