Iriver h140 play & stop produces small klicks

[audioholic]

Hey to everyone,
i updated my iriver h 140 to the build r14450.
Everything seem to be fine except:
If i press stop or pause while playing a file ,i can hear a small klick on my headphone.
I do not know since build this happens, cause i updated from one
last year and there was no problem.

Maybe someone has the same problem ?

Many thanx
