| * Fix to support mono in effect buffer allocation.Ricardo Garcia2014-08-111-1/+4
| | | | | | | | | | | | | | | | Since effects are now enabled for recording, mono cases are possible and needed to be correctly allocated. Bug: 16917961 Change-Id: I760fc421f9f90fabb3f0deadd5f9dc61cd284371

* audio policy: enable more than one sink per audio patch.Eric Laurent2014-08-081-29/+35
| | | | | | | | | | | | Allow creation of audio patches with more than one sink. More than one sink is enabled when: - Connecting an input device to output devices on the same audio HW module. - Connecting an output mix to output devices on the same audio HA module. All other patches are limited to one sink. Bug: 16879363. Change-Id: I95be6948ef29df64e51e5b8ace38c2db7f3e89f2

* | audio: fix crashes upon USB device connectionEric Laurent2014-08-051-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Audio policy: Replace unknown device assertion by debug log in setDeviceConnectionState(). It is possible that some kernels indicate connection of a legacy device type when a USB audio device is connected. We should just ignore this device. - Audio flinger: Make sure FastMixer thread is idle before exiting the normal mixer thread and closing the output stream.

* | Remove 64-bit android_atomic uses from StateQueue.Hans Boehm2014-07-312-12/+8
|/ | | | | | | | | | Use stdatomic.h instead. We're trying to remove android_atomic use wherever possible. The 64-bit uses seem easiest to remove first. This cleans up the code, though not as much as C++ <atomic> would, if it worked everywhere.

* audio flinger: add patch connection between hw modulesEric Laurent2014-07-2410-216/+855
| | | | | | | | | | | | | | | | | | Add support for audio device connections between different audio hw modules. The patch is performed by creating a bridge between the playback thread connected to the sink device and the record thread connected to the source device using a pair of specialized PlaybackTrack and RecordTrack. - Added PatchTrack and PatchRecord classes. - Added TrackBase type to indicate more clearly the track behavior. - A TrackBase can allocate the buffer or reuse an existing one. - Factored some code in openOutput() and openInput() for internal use by PatchPanel.

| * Move AudioRecord frame count calculations to serverGlenn Kasten2014-07-171-35/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Buffer frame count and notification frame count are now calculated by server instead of by client. The server has more information and can do a better job. Also fix a few bugs: - If a fast track was re-created, even with same pipe depth, it would fail. Now it can correctly re-create a fast track provided the pipe depth is same. - Notification frame count for fast tracks was calculated by client as 1/2 of the total frame count, which is a large value due to the pipe. Now the notification frame count is set by server to the HAL frame count. This should reduce latency for fast tracks. - EVENT_OVERRUN were happening frequently when there was sample rate conversion, because the client didn't know about the sample rate conversion, and under-estimated the necessary buffer size. Now since server calculates the buffer sizes, EVENT_OVERRUN is unlikely. - RecordThread::createRecordTrack_l was checking for mono and stereo for fast tracks. This is not necessary, and now we can handle a multi-channel fast track. Bug: 7498763 Change-Id: I0c581618e8db33084d5ff9ed50a592990c9749e8
