* Extend downsampling ratios greater than 2:1Andy Hung2014-08-112-4/+4
| | | | | | | | | Also improve robustness to choice of sampling rate or buffer size such that increasing either by 10x does not cause overflow. Bug: 12979141 Bug: 15933066 Change-Id: If7989bd745d1bee3bdf811b8b7c978543ccafb65
* 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

AudioResampler is updated to take floating point volume to match. Both legacy integer and floating point mixer engines work. For now, integer volume is used when the new mixer engine runs in integer input mode, for backward compatibility with the legacy mixer. The new mixer engine will generally run in floating point input mode. When the legacy path is removed, the integer volumes will be removed. Change-Id: I79e80c292ae7c8b8bdd0aa371a1b2c3a1b618290
