The mechanism delaying notifications in case of
muliple active outputs with long latencies must
take into account recently paused audio tracks.

The volume and routing policy of AUDIO_STREAM_ENFORCED_AUDIBLE is
now controlled by AudioService by means of new forced use type
AUDIO_POLICY_FORCE_FOR_SYSTEM with config
AUDIO_POLICY_FORCE_SYSTEM_ENFORCED.
Property ro.camera.sound.forced is not used anymore.

Changes for new audio devices enums:
- legacy audio HAL wrapper provides conversion between new and
old device enums. It exposes a rev 2.0 audio device API to the
audio framework and allow legacy implementation to use old device enums.
- AudioPolicyManager: use standard enum value for no device (0).
Change-Id: I855d72291d672cdd8a6641bedb228634a54b7d9d
Define a new forced mode to route media to remote submix.
Update media routing rules according to mode.
Modify device connection management for remote submix.
Note that this CL doesn't implement changes to not prevent audio
recording when WFD is on, as audio recording is currently limited
to one input.
Change-Id: I458fe1802705da2d091ff82e536dc3e7f092f291
The AudioPolicyManagerBase implementation was using some device
enum values from AudioSystemLegacy.h, of type audio_devices,
and some from /system/audio.h, of type audio_devices_t.
Now only uses audio_devices_t, and associated functions to
inspect what audio device type they correspond to.
Added #define to represent "no audio device" to clarify code.
Removed unused variable in AudioPolicyManagerBase::startOutput()

The fields for the lists of input and output IOProfile are

When an HDMI sink is connected it is possible that
a direct output is made available for multichannel audio.
In this case, the list of outputs available to reach the HDMI device
after the connection is different from before. checkOutputForStrategy()
must take this into account in order to invalidate tracks so that
they can be re connected to the multi channel output if necessary.
Change-Id: Id0baeb51688eba8017fe96bf92aaac52eb8e0f59
Add the capability to query supported parameters for
direct outputs after a device is connected. This allows
to dynamically update the output profile for devices like
HDMI where the capabilities depend on the connected sink.
Also added very verbose log mode for volume and mute.
Change-Id: I1d4ba8e7dbc3e1af883582857ce93240441e551c
Added FORCE_NO_BT_A2DP forced use to allow applications to

When switching audio path, it is sometimes required
to temporarily mute certain streams to avoid glitches.
The unmute command is sent with a delay but the volume applied
when unmuting is computed according to the state at the time of mute.
If the device selection changes after the delayed unmute is programmed
the new volume will not correspond to the new device.
setStreamMute() now accepts a device selection as input parameter which is
used instead of current device for volume computation.

set_last_user_activity_timeout() is no longer used or useful.
It opens a sysfs node that no longer exists that used to
be published by a daemon that is no longer even compiled
and that is about to be deleted. It used to be called
by the power manager with a huge value whose purpose was
essentially to disable the timeout feature altogether.
Long live dead code!
Bug: 6435382
Change-Id: If8f97a66f4e963a11e1c6b67ad97b41b2613043e
Added specific volume curves for AUDIO_STREAM_SYSTEM,
AUDIO_STREAM_ENFORCED_AUDIBLE and AUDIO_STREAM_DTMF.
Volume for these streams tracks AUDIO_STREAM_RING on phones
and AUDIO_STREAM_MUSIC on tablets but is contrained in the range
-24dB to -6dB on speaker and -24dB to -12dB on headset.
STRATEGY_ENFORCED_AUDIBLE routing policy is now the same as
STRATEGY_MEDIA in countries where not enforced.

The addition of the per device volume feature has introduced
a problem where a volume burst can be heard in the headphones
just after insertion if the speaker volume is much higher than the
headphones volume.
Added a temporary mute of the output when switching device to force
volume ramp to 0 and back up to new volume.

Change-Id: I5c9ffbbcadd12d25c78cc2614d351346b8186c55
Added definitions for parsing deep buffer flags in output profiles.
Make sure that sound start is delayed enough to allow
duck/mute effect to apply before starting a notification on an output
with lower latency.

Audio hw modules are now loaded according to configuration
data read from audio_policy.conf. They are not loaded anymore
from a hardcoded list in AudiFlinger.
Output and input streams are opened on the hw module by which
they are exposed.
Also removed obsolete "acoustics" flags for input streams.
Change-Id: I8dc658cc83890d3ac7d5e36c372a03732aa5b0c4
The audio policy manager implementation now reads a configuration file at
boot time that contains descriptors for available audio hardware
modules and for each module the profiles of available inputs and outputs streams.
The configuration file path on the target is: /system/etc/audio_policy.conf.
A default configuration file is given that defines a basic configuration
with one primary audio hw module capable of playback and capture.
Each platform or device should have its own audio_policy.conf file.
Also removed default value of fromCache argument of getDeviceForStrategy()
and getNewDevice() methods.

Map the NOTIFICATION stream type to a new strategy,
named STRATEGY_NOTIFICATION_RESPECTFUL, which differs
from STRATEGY_NOTIFICATION in that, when media is
playing, the notifications will use the same output
as the MEDIA strategy. This will results in the
notifications not being duplicated on the speaker
when a headset is in use for media playback.

This change makes support for A2DP related audio policy more generic:
-removed WITH_A2DP compilation switch
-use output profile descriptors listing the parameters
(sampling rate, format...) devices and attributes (low power, tunneling...)
for each available output.
All the behavior specific to A2DP is derived from the A2DP output profile
descriptor.
- removed obsolete a2dpUsedForSonification() method.
This is a first step towards a more generic support for different audio
hardware modules (USB, HDMI) and output streams supporting different
combinations of parameters (sampling rate, format...) and attributes
(low power, tunneling...).
Ultimately, the hw modules and output descriptors will loaded from a
configuration file.

Improve volume management by keeping track of volume for each type
of device independently.
AudioPolicyManagerBase now keeps track of stream volumes for each device
and apply volume according to current device selection.
Methods to set and get stream volume now specify the device class.
A value for "default" device is always present for each stream and is used
if a device is selected and no specific volume was ever set for this device.

Make sure that camera shutter sound is output to device speaker also while
in call.
Added a new strategy for enforced audible stream to address this case as
the routing policy is now different from sonification strategy.
Issue 5548406.

Add a default implementation of get_next_write_timestamp to the C <--> C++
legacy audio HAL implementation allowing HALs using the legacy C++
AudioStreamOut to overload and implement get_next_write_timestamp. Default
implementation returns INVALID_OPERATION to indicate that the functionality is
not supported.

When no DRC is applied by the platform when playing
over the device speaker, faint audio signals are not boosted and
barely audible until the media volume is raised to about one fourth
of the range.
Compensate this by applying a different volume curve for music stream
when the speaker is selected.
Change-Id: I03f316fb28150eda50b05dfa12310701e2674648
Modified the volume curve for ringtones and notifications
in audio policy manager. The first volume step now corresponds to
-30dB instead of -50dB thus making ringtone much more
audible for low volume settings.
Also made a generic implementation of volume curves according to
audio policy strategies.
