* audio HAL: reverse mutex locking orderEric Laurent2015-06-191-26/+51
| | | | | | | | | | | | Do not use main audio HAL mutex but a specific stream mutex when preventing control thread starvation by playback or capture threads. This will prevent systematic locking of main HAL mutex in read ot write and avoid glitches. Bug: 21880828. Bug: 18489202. Change-Id: I3054e0d93b823bd9d2fb84a49e9c5bbbe728262a

| | | | | | | | | Eliminated unnecessay locking/unlocking in adev_set_parameters(). Corrected and simplified lock/unlock order in out_write() and in_read(). Bugs 19363750 Change-Id: Iede9a95f5f17645d9780b344fd5ee009cd9fa94d

| | | | | | | | | | Also clean up logging. This doesn't completely fix the referenced bug, but substantially reduces the instances of long latency on USB device disconnect. Bug: 19363750 Change-Id: If0a6d64c4973277ae2474e121198e47df973965e
* Technical Debt Paydown - move/rename filesPaul McLean2015-01-1310-1096/+6
| | | | | | | | Moved audio (alsa actually) utils files to system/core/alsa_utils. Renamed "audio" utilities to "alsa" to better relect their purpose. Renamed audio_hw.c -> to audio_hal. c to better reflect its purpose. Change-Id: I67c7d47ee02abafd3e12c4c99d605a62e0f59122

| | * usb audio: Fix incorrect bytes returned for recordingPavan Chikkala2015-01-091-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a recording session , the number of bytes read is not updated when pcm_read() fails. This results in silence/invalid data being added during a device switch from USB headset to handset. Fix is to reset the number of bytes read if pcm_read() returns an error indicating removal of USB headset. Bug: 18611518 Change-Id: I10d578c3cf1037c90a891e63be2bd1c2b7e6126b

| | | | | | | | | | | | | | | | | | | | tinyalsa fails to retrieve the correct value for the period count from the f_audio_source driver and tries to use zero instead. This wasn't a problem before because the usb audio HAL used hard coded values that were compatible with the driver. Bug: 16799652 Change-Id: I6f5b907a0699c58b071e9f419ed8e053a7d9dc77
