2014-08-12Tinyalsa: allow pcm_wait to wait on POLLIN eventsApelete Seketeli
Tinyalsa pcm_wait() function does not wait on POLLIN events, preventing it to be used when recording audio data. This allows pcm_wait to wait on POLLIN events.

2014-08-12Tinyalsa: standardize error message for wrong input valueBaptiste Robert
Currently, if a user sets a mixer with a percentage value greater than the maximum, tinyalsa does not inform the user about this "error" and silently replaces the user's value by the maximum. However, if a user sets a mixer with an integer value greater than the maximum, tinyalsa informs the user with an error. This patch purpose is to define the same behaviour in both quoted cases: user is informed through an error.

2014-05-06Mixer: Check validity of input valueBaptiste Robert
When the user wants to set a mixer with a value greater than the maximum or smaller than the minimum, the mixer is set at an undefined value. This patch set purpose is to return a error if the input value is out of range.

Add separate call for pcm prepare
2014-04-29tinyalsa: add separate call for pcm prepareOmair Mohammed Abdullah
Tinyalsa combines PREPARE and START calls to the driver in the pcm_start() function. Typically, this is needed for making a driver allocating hardware resources that are not related to a PCM stream.

2014-04-22Add a function to disambiguate duplicate control namesFrédéric Boisnard
Control names are not unique and can be shared by multiple mixers controls. When this happens, there is no way of accessing the mixer using its control name, because mixer_get_ctl_by_name() always returns the first match. The only way of accessing the mixer is through its control number, i.e. using mixer_get_ctl(). This patch adds the function mixer_get_ctl_by_name_and_index() to offer the possibility to retrieve a control through its name and index. This index corresponds to the nth occurence of the control name in the global supported controls names list.

2013-11-19tinymix: Improve detect of integer valuesCharles Keepax
Tinymix detected integer values when setting controls simply by calling isdigit on the first character of the value being set. This causes problems with enumerated controls whos values start with digits. This patch improves this to provide more robust detection of integer values.

2013-09-03pcm_get_htimestamp can now use CLOCK_MONOTONICGlenn Kasten
Previously the timebase was not documented. Now a new pcm_open flag can be used to specify the clock. If flag PCM_MONOTONIC is specified, then pcm_open uses SNDRV_PCM_IOCTL_TTSTAMP with parameter SNDRV_PCM_TSTAMP_TYPE_MONOTONIC to request timestamps in CLOCK_MONOTONIC.

2013-08-13tinycap: support streaming captured PCM to stdoutRichard Fitzgerald
It is sometimes useful for testing to be able to stream the captured PCM to another tool instead of being forced to save it to a WAV file. Using '--' instead of the target filename will send the raw PCM to stdout (without any header). Signed-off-by: Richard Fitzgerald <rf@opensource.wolfsonmicro.com>

2013-07-17pcm: support S24_LE formatSimon Wilson
S24_LE is 24 bit audio in a 32 bit sample size. Also make the pcm_format_to_bits() function part of the API since it will be required for tinycap.
2013-06-28mixer: add mixer_get_name() APISimon Wilson
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.
