Previous code was clearing the buffer after\ncalling the process functions and  when transitioning from active\nto inactive, the last processed buffer was passed again once to effect\nprocess function before being cleared.\n\n2 - Fixed potential mutex cross deadlock when disconnecting an effect\nwhile playback is active. This is because EffectChain::process_l()\nwas calling PlaybackThread::hasAudioSession() thus creating an inversion\nin the mutex lock order (EffectChain mutex locked before ThreadBase mutex).\nThe fix consists in removing the call to hasAudioSession() from process_l()\nand requires each effect chain to keep count of the number of audio tracks\nattached to it (previously only the active tracks were accounted for).\n\nChange-Id: Iee4246694ea8c7a66c012120c629d72dd38f9c35\n"

The only problem for playback was that the initial\nphase fraction was wrong when restarting a track after stop (it was correct after a pause).\n\nChange-Id: Ifc2585d685f4402d29f4afc63f6efd1d69265de3\n"
