The problem is that the AudioService is not notified of the death of
IAudioFlinger binder interface because no methods was called on AudioFlinger
from system_server since the device booted. Therefore, AudioSystem did not created any
IAudioFlinger interface in the system_server process.
The root cause was always present but more likely to happen on a tablet than on a phone
as for instance no beeps are played when volume is adjusted.
The fix consists in having AudioSystem explicitly call a method on AudioFlinger when a
callback is installed to make sure that an IAudioFlinger binder interface is created
regardless of any other activity in the client process.

Modified default volume control logic in AudioService:
1 IN_CALL volume if in video/audio chat
2 NOTIFICATION if notification is playing or was playing less than 5s ago.
3 MUSIC
Modified silent mode:
- now also affect MUSIC stream type
- entering silent mode when VOL- hard key is pressed once while selected
stream volume is already at 0 (except for VOICE_CALL stream).
- exiting silent mode when pressing VOL+ hard key while in silent mode
Play sound FX (audible selections, keyboard clicks) at a fixed volume.
Modified audio framework:
- isStreamActive() method now implemented in AudioPolicyManagerBase (previously AudioFlinger)
- iStreamActive() now specifies a time window during which the stream is considered
active after it actually stopped.

The audio mode MODE_IN_CALL signals the system the device a phone
call is currently underway. There was no way for audio video
chat or VoIP applications to signal a call is underway, but not
using the telephony resources. This change introduces a new mode
to address this. Changes in other parts of the system (java
and native) are required to take this new mode into account.
The generic AudioPolicyManager is updated to not use its phone
state variable directly, but to use two new convenience methods,
isInCall() and isStateInCall(int) instead.

Modified AudioService.getActiveStreamType() so that STREAM_VOICE_CALL is selected when a track using this stream
type is playing.
Chanded isMusicActive() for a more generic isStreamActive(stream) method in AudioSystem, IAudioFlinger and AudioFlinger.
Add new config values to AudioSystem::FOR_DOCK force usage to differenciate car and desk docks.
Use a receiver for the sticky Intent.ACTION_DOCK_EVENT in AudioService to detect the type
of dock and select force usage accordingly.
to the AudioPolicyManager a new forced usage AudioSystem::FOR_DOCK
which can take the FORCE_NONE, FORCE_BT_DOCK or FORCE_WIRED_ACCESSORY
values. This CL is complemented by an update of the APM to take into
account the FOR_DOCK usage.
The headset state indicated by HeadsetObserver in the broadcast intent ACTION_HEADSET_PLUG was not 0 or 1 as specified in the java doc but contained a bit field indicating the type of headset connected.
Modified HeadsetObserver to broacast a state conforming to java doc.
Added an extra to intent ACTION_HEADSET_PLUG to indicate if headset has a microphone or not.
Removed handling of non standard headset indications from HeadsetObserver.
Removed platform specific devices from output devices defined in AudioSystem.
Modified AudioService to use new ACTION_HEADSET_PLUG intent extra instead of bitfield in state.
Initial commit for review.
Integrated comments after patch set 1 review.
Fixed lockup in AudioFlinger::ThreadBase::exit()
Fixed lockup when playing tone with AudioPlocyService startTone()
AudioTrack, AudioRecord:
- remove useless mAudioFlinger member of AudioTrack and AudioRecord.
- signal cblk.cv condition in stop() method to speed up stop completion.
- extend wait condition timeout in obtainBuffer() when waitCount is -1 to avoid waking up callback thread unnecessarily
AudioFlinger:
- remove some warnings in AudioFlinger.cpp.
- remove function AudioFlinger::MixerThread::removetrack_l() as its content is never executed.
- remove useless call to setMasterVolume in AudioFlinger::handleForcedSpeakerRoute().
- Offset VOICE_CALL stream volume to reflect actual volume that is never 0 in hardware (this fix has been made in the open source): 0.01 + v * 0.99.
AudioSystem.java:
- correct typo in comment
IAudioflinger, IAudioFlingerClient:
- make AudioFlinger binder interfaces used for callbacks ONEWAY.
AudioHardwareInterface:
- correct routeStrings[] table in AudioHardwareInteface.cpp
