2013-06-28mixer: add mixer_ctl_update() APISimon Wilson
Some sound cards update their controls due to external events, such as HDMI EDID byte data changing when an HDMI cable is connected. This API allows the count of elements to be updated.
2013-05-07mixer: add get/set_array APISimon Wilson
This replaces (and extends) the existing get/set_bytes API, which is no longer required.
2012-12-18Clean up asoundlib.h header fileRom Lemarchand
Remove unused constants and unimplemented functions.
2012-12-03pcm: add pcm_get_params APISimon Wilson
This enables the capabilities of any given PCM to be queried. Created with input from Priyesh Bisla and Gabriel Beddingfield.
2012-10-24mixer: Add mixer_ctl_{set,get}_bytes()Dimitris Papastamos
For binary controls we don't want to go through mixer_ctl_{set,get}_value() as that will trigger many calls to our get()/put() callback in the kernel. Set the entire payload at once and trigger the get()/put() callback once. Signed-off-by: Dimitris Papastamos <dp@opensource.wolfsonmicro.com>
2012-10-22Add pcm_wait() to the tinyalsa API.Gabriel M. Beddingfield
2012-10-22pcm: Add support for S8 and S24LE formats.Gabriel M. Beddingfield
2012-05-04pcm: Add PCM_NORESTART flagJohn Grossman
Add a flag which can be passed to pcm_open (called PCM_NORESTART). When set on a playback stream, calls to pcm_write will not automatically attempt to restart an ALSA device in the case of an underflow. Instead, it will propagate the first EPIPE error up to the application to allow it to handle the underflow situation. Subsequent calls to pcm_write will attempt to start the pipeline.
2012-03-08mixer: simplify string get APIsSimon Wilson
Just like the pcm_get_error() API, simplify the mixer API functions to return pointers to constant strings instead of making copies of strings.
2012-02-10pcm: Constify write buffersMark Brown
Mark the write buffers as const - they won't be modified and this is friendlier to applications.
2011-10-27include: fix header comments and argumentsPierre-Louis Bossart
Comment on buffer size was wrong. Argument to bytes_to_frames is bytes, not frames
2011-10-13pcm: add mmap playback and no periodic IRQ support.Liam Girdwood
Add mmap playback and no period IRQ support to pcm core.
2011-07-27pcm: add control for ASLA thresholds to pcm_openJohn Grossman
Add the ability to explicitly set start, stop and silence thresholds during tinyalsa's pcm_open. Setting any of these values to 0 in your pcm_config structure will cause the system to use its old defaults.
2011-07-27include: make it easier to use this header from C++John Grossman
Add a extern "C" controlled by an #ifdef __cplusplus directive so that this header can be included from C++ code without having to explicitly control the linkage.
2011-07-27Merge pull request #2 from broonie/add-includetinyalsa
include: Add a local asound.h to allow build with current public releases
2011-07-25pcm: add pcm_get_htimestamp() functionEric Laurent
pcm_get_htimestamp() returns the number of available frames in the kernel driver buffers as well as the corresponding high resolution time stamp.
2011-07-21include: Add a local asound.h to allow build with current public releasesMark Brown
Bionic does not ship a copy of asound.h and it should do no harm to have a local copy here.
2011-06-24pcm: add pcm_start/stop() functions for streamsSimon Wilson
This is essential for streams such as loopback devices that do not transfer data.
2011-06-06Add integer range getters to mixerSimon Wilson
2011-06-05Implement mixer setting in tinymixSimon Wilson
- re-add function to set enum type by string - implement setting of mixer values in tinymix - fix bug: read current mixer values before writing
2011-06-05Add enum support to mixerSimon Wilson
- simplify interface for setting/getting enum values - implement enum string get function - update tinymix to deal with enums - rename set/get_int functions because of supported types
2011-06-04Improve mixer supportSimon Wilson
- support get/set of multiple values - add parameter checking to functions - add api function to get control type - add tinymix utility to list mixer controls
2011-06-02Support multiple cards and devicesSimon Wilson
2011-05-25Initial contributionSimon Wilson
