Yes, you have to stop the source. If you want to modify/delete a buffer, it
has to be detached from the source (call alSourcei(source, AL_BUFFER, 0); on
all sources it's currently set on), which can only be done when the source is
stopped. You can also just set a different buffer on the source (which
implicitly detaches the previous buffer), while it's stopped.
