I practised for ages on not doing that when i started playing. I tried to not make a single T sound when playing any notes as i found it made me sound too separated from the instrument. Try tounging with the very very tip of your tongue and really gently touching the tip of the reed.
I seem to have developed a problem recently of squarking on the start of each note.
Not all of the time but alot of the time.
Im thinking its my umbouchure but I would like some help if possible
