- Use a constant input level to the reverb engine and implement volume control in the insert reverb. This avoids the volume spikes when an effect that was inserted after the reverb is disabled or removed. - Fix clicks (one silent buffer) at the end of the reverb disable period. - Modified volume management in audioflinger so that the volume ramp is also done by the insert effect if present when the track is paused (avoids clicks). - Increased room level for all presets. Also fixed problems with output stage session (-1): - effect bundle wrapper was not designed to support session -1 - the permission check in audioflinger for using session -1 failed due to a wrong usage of getCallingPid() Change-Id: Id1ff51327263364bf71d3f2668fa5cde4311d84f
