| | | | | | | | | | | | | | | | | | | | | | Bring playback and capture buffer size back to their initial size. Current size was dictated by constraints in early voice processing implementation but is not necessary anymore. Increasing buffer size will help in power consumption and limit possible occurence of audio skipping during playback and capture. Change-Id: I7837c62e11700ed5c9a26f52fb27170add09721d

| * Fix issue 4126225: setMicMute() execution timeEric Laurent2011-03-171-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | The cause is that the thread executing setMicMute() can wait for several seconds before acquiring the input thread mutex when audio capture is active. The fix consists in forcing a sleep of the capture thread when standby() (called by setMicMute()) wants the mutex. Applied the same fix to output stream and to setParameters() function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that the AudioPolicyManager refreshes the device attached to the hardware output stream every time another output stops (in this case A2DP output). As there is no active stream on the HW output, the selected device is 0. As the shutter sound is short and there is some additional delay to setup the A2DP output, the sound is not yet out of the AudioFlinger mixer when the device is set to 0. On Crespo, device 0 is a valid audio path (means audio off) which is not the case on other platforms and therefore the output is disabled while the shutter sound is actually playing. The fix consists in ignoring requests to set the output device to 0 in the audio HAL. Change-Id: I7366e359a7d3a0f8207e7a5c879ced9078224002

| | | | | | | | | | | | | | | | | | | | | | | | Rely on the audio input source parameter for mixer configuration. The generic APM implementation now passes the audio recording source as a configuration parameter, and uses the enum defined in mediarecorder.h. But the driver uses a string to define the "input source state". This change maps the input source to the string used by the driver. Change-Id: I5fce44579a3cda01ed73f67fb8c3091ef05cce76

| * Fix issue 3305305.Eric Laurent2011-01-182-16/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that when the voice search tone is started, audio capture is still active and the output stream write function needs to place the input stream in standby to reconfigure the kernel driver. To do so it has to acquire the input stream mutex but as the input stream thread holds the lock most of the time while sleeping in the driver waiting for more data, this is very difficult and can take several seconds. The fix consists in forcing a sleep in the next read() when another function needs to acquire the input stream lock. The same change is done for output stream write() function. Also removed the workaround for issue 3201189 in setMode() (thread priority bump) as this change addresses the same problem. Change-Id: I3a5e672717752f83dfedce822a18748b165b0a5a

* Issue 3058745: fix audio HAL downsampler.Eric Laurent2010-10-181-6/+9
| | | | | | | | | | | Latest audio HAL downsampler implementation had a problem that caused one sample to be dropped if the input buffer size was odd while downsampling by a factor of 2. This explains why record timing was correct for 22 and 16kHz but not for 11 or 8kHz: in the later case, the second stage of resampling (22 to 11) receives 503 frames for each buffer.
