To simplify format negotiation and volume control in decoder, I was
thinking if it was possible/a good idea to make the decoder part of the
filter chain as the first filter? Or alternatively insert a "dummy"
filter that translates the AF_CONTROL to ADCTRL_... Unfortunately I
don't see a way to do this without making it a hack, as af currently
can't directly access ad... Any ideas/suggestions?
