Hi all; I'm dealing with a quite complex AUGraph and I'm trying to switch the file an AUFilePlayer is playing; I did stop the AUGraph, Uninitialize it and changed the filePath of the audioURL, opened the audioURL with
AudioFileOpenURL but I do receive -50, Error: AudioUnitSetProperty[kAudioUnitProperty_ScheduledFileIDs] failed (-50) to be exact.
An almost similar method however is loading the file (the exact same file) into the AUFilePlayer unit in the setup procedure and everything is working smooth until I try to switch audio file.
My question is: what is the right procedure to change audio file for a instantiated AUFilePlayerUnit? does it also involve AUGraphDisconnectNodeInput to disconnect the Unit from the Mixer (yes I'm also using a mixer unit where the AUFilePlayer Unit is connected ) ?
Probably the answer is very easy and I'm too tired at the moment to hel myself.
tnx in advance
