Thank you for the explanation regarding the "save all settings" in the audio settings. Now I understand why is needed to check for the desired card and choose it when the patch is loaded.
Regarding the block size - I don't have my pi running at the moment but I remember that last time I run it I needed to set the block size to 512 because lower then that was producing some undesired clicks. Does it make sense?
I would like to have the ability to change the block size when patch is loaded and therefore I will be happy if you can show me how to do that in that patch whenever you can.
Thanks for all the explanations!
edit: If we are already in that topic; I have seen two parameters I don't get in the audio setting menu - callbacks and delay(msec) what are the two for and what they should be?
