Despite my best efforts I am still getting a light rattling distortion sound on my core audio app when recording with the 6s in speaker modeI've read all the other posts on 6s 48000 mic issues and believe i am doing everything correctly - I'm setting up my graph and client formats correctly as far as I can tell , and not expecting a certain number of frames any where in my codeMy app needs to use core audio run at 44,100 because it mixes the live mic with sampled content that is 44100.0It also needs to have the AVAudioSessionCategoryOptionDefaultToSpeaker flag set because it monitors audio out of the speakers when the mic is off Here is a scaled down example - I'm connection the remoteIO input -> mixer -> remoteIO in typical fashion and setting the stream formats here is what my initialized running augraph looks like in the consoleAudioUnitGraph 0x599000: Member Nodes: node 2: 'auou' 'rioc' 'appl', instance 0x136fbafc0 O I node 3: 'aumx' 'mcmx' 'appl', instance 0x1380
