Joe Sansalone 6 Posted February 15, 2022 Hi, I used some CoreAudio translated files back in Delphi 10 (Seattle) and they worked great. Now, in Delphi 11, they compile but there's a problem with the audio .. no audio is produced. So I'd like to see the original Apple source code for these functions/structs etc, in order to make sure that I have the correct translation to Object Pascal. Where do I get the source for the AudioToolbox framework? Does XCode come with source? Joe Share this post Link to post
