I'll try to be more understandable I'm sorry about that.
In fact the patch don't change anything. For exemple, when you recive a brand new Axoloti-core, if you do this patch :
And plug an audio input into the stereo input of the axoloti. You'll get sound only if you turn the dial. That's what I'm looking for.
But since I've placed this object "audio/inconfig" on my patch : 
My audio input signal is "Thru", it means even if the dial is on 0, I hear the exaternal audio signal like if this dial was at 64. And I can't find any way to go back at the defaut audio input set-up. Even if I remove this object, or try different config on it.
I read somewhere from Johannes that this object set-up "forever" the audio input preferences of the board. Even if you delete this object, the board will keep this preferences until you change them again. But I'm just wandering how can I get just the original factory audio input preset to recover the audio input signal not as an audio "Thru".
That's my problem... I'm I more clear with this ?
