* audio: add 24000 Hz capture sampling rateEric Laurent2012-06-131-1/+1

* audio: workaround for hdmi multi channel swapEric Laurent2012-06-111-0/+11
| | | | | | | | | | Workaround for HDMI multi channel channel swap on first playback after opening the output stream: force re-opening the HDMI pcm driver after writing a few periods. Bug 4282214. Change-Id: Ibe1452a8905a27bc3f95564a45cfb9bb490b65ae
* audio: add support for multichannel HDMIEric Laurent2012-06-012-13/+248
| | | | | | | | | Added a dedicated audio output stream for multichannel HDMI. This output stream is used when an HDMI sink supporting 6 or 8 PCM channels is connected and 5.1 or 7.1 multichannel content it played. Change-Id: I7ad1cd6be4c2b3a9e24a4811aa87e7223badedc4
* audio: variable deep buffer sizeEric Laurent2012-05-141-20/+92
| | | | | | | | | | | Add back the capability to change the deep buffer size according to screen state. This solves various issues related to audio focus, volume and pause control that arise with large audio buffers. Those issues should be ultimately addressed by changes in the audio framework.

* audio: fix media volume issues.Eric Laurent2012-05-101-24/+88
| | | | | | | | | | | | | | | Fixed 2 issues with media volume: 1 - since we use mm port for music and tones port for other use cases the digital volume should be applied to both "DL2 Tones Playback Volume" and "DL2 Media Playback Volume". 2 - the total gain applied to audio originating from the AP is the combination of digital gain in ABE and analog gain in codec. Some use cases like telephony have a higher priority than media and apply a different (higher) analog gain. As this analog gain is common to all sources, digital media gain should be adjusted accordingly to avoid volume bursts while in call and playing music. This is particularly important in speaker phone mode. Change-Id: I90200282edca7098603edca2d56821290988cb20
* audio: fix memory leak.Eric Laurent2012-05-021-4/+8
| | | | | | | Fixed memory leak introduced by commit 4e7a573f in case of error in adev_open_output_stream(). Change-Id: I4acc070d748cea228da846f95c7826160e0196a5
* audio: add support for deep PCM bufferingEric Laurent2012-04-302-121/+237
| | | | | | | | | | | | | | | Implement one output stream with short buffers and one output stream with deep buffers. The stream with short buffers is selected for most use cases and provides short latency. It uses TONES_DL port and IOCTL write mode. The stream with deep buffers is used for music playback. It uses MM_DL port and MMAP NOIRQ write mode. The deep buffer stream is not used when the device selection is BT SCO, HDMI or SPDIF. The echo reference is only taken from the short buffer stream.

* Adjust output buffer size and sample rateGlenn Kasten2012-04-271-10/+78
| | | | | | | | | | | | Use 4 buffers of 96 frames each = 4 ms at 48 kHz. Keep the 44.1 kHz -> 48 kHz up-sampler in HAL. Disable mmap mode and non-IRQ mode; this gives better variance for cycle times. Reduce number of buffers from 4 to 2, works OK in non-mmap mode but not mmap mode. Update comments based on code review. Tested with audio input. Not yet tested with echo cancellation. Change-Id: I69db00ab408cd2aad5788d602eb01fc0c7e4e78b

* audio: add dual mic support for pre processingEric Laurent2012-04-101-101/+584
| | | | | | | | | | | | | | | | Added support for audio pre processing libraries implementing dual mic solutions. When a pre processor is enabled, its multi channel capabilities are queried and compared to capture channel combinations supported by the device and other enabled pre processings. The most favorable configuration is chosen and pcm capture driver is restarted with the appropriate channel config. Also made various capture and process buffers naming and allocation more consistent. Change-Id: I90be4798951d0a34dc77d6bdc93ef15cad3ff5af

* audio: fix audio drop when speaker is selected 2.Eric Laurent2012-04-021-1/+2
| | | | | | | | | | | Commit 78a7609d fixed audio drop at the start of ringtone. This commit fixes another similar issue with camera shutter sound being dropped while in call over headset. There was a workaround for this second issue in audio policy manager but this was not satisfactory as it was impacting all devices for a problem that is Prime specific.

| * audio: fix audio drop when speaker is selectedEric Laurent2012-03-161-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | When changing audio path to speaker while playback is active, several hundred ms of audio are dropped. This is mostly noticeable when a ringtone starts playing. This change is a workaround forcing the output in standby when speaker is selected. The root cause must still be indentified and fixed.

* | audio HAL: support for low power audioEric Laurent2011-10-141-42/+96
|/ | | | | | | | | | | | | Implement a mechanism to dynamically switch between short and long buffers in kernel pcm driver. Using long buffer significantly decreases power consumption at the expense of latency. Therefore a hint is given to audio HAL by AudioService indicating when the screen is off and low latency is not required any more because neither video playback, VoIP/video chat or any user interaction is expected. This mechanism relies on the support for MMAP and NO IRQ write modes in tinyalsa. Change-Id: Ida9216a141750137a0592187e24a68f263ef3fbe
