Werner is quite sure that the problem is that on a 2MB card the
Audiobuffer is not big enough. With a 4MB card he had room for more
Buffer so that here the Problem should not occour. 

IIRC Werner told me there are on a 2MB card only space for 37ms audio -
that is not much ;) and on a 4MB card he has 170ms space.

But we should try the bigger ringbuffer before giving up :)
