I absolutely understand ZennDarkfire's problem (especially in the case of the War Doctor sonic, because it is the most screen accurate one). I love the newly added classic sounds but it bugs me that they added the same sound chips to all of their newly released sonics and the sounds are circulating, so I can't use the same sound twice properly. I get it that it's for budget reasons, but couldn't they just reproduce the chips from the previous runs, and put them into the 10th, Future and War doctor sonics, and the new chips with only the classic sounds to the 3rd and 4th ones?
I tried it with my 4th Doctor sonic, I want it to only play the 3rd an/or 4th sound. I took out the batteries after playing the 3rd sound, held down the spring loaded switch, put the batteries back. It played the first sound. Tried again, it played the first sound again (but after that the sounds circulated).
