Bookmarks and microphone

I like to use the bookmark function and
then the microphone to listen to my
scriptures on my iPhone and iPad. For a
few weeks now, the microphone only reads
from beginning to end of the chapter no
matter where the bookmark is that I have
selected. it shows the bookmark is there
but it will not read from the bookmark. It also
will not advance or go back with the
10 sec icons. Help!!! Thanks!
