2015-08-26tinypcminfo: make function pcm_get_format_name() staticThomas Petazzoni
When building tinyalsa with gcc 5.x, the following warnings appear: tinypcminfo.c:97:52: warning: 'format_lookup' is static but used in inline function 'pcm_get_format_name' which is not static return bit_index < ARRAY_SIZE(format_lookup) ? format_lookup[bit_index] : NULL; ^ tinypcminfo.c:97:35: warning: 'format_lookup' is static but used in inline function 'pcm_get_format_name' which is not static return bit_index < ARRAY_SIZE(format_lookup) ? format_lookup[bit_index] : NULL; And the build fails with: tinypcminfo.o: In function `main': tinypcminfo.c:(.text+0x2f0): undefined reference to `pcm_get_format_name' collect2: error: ld returned 1 exit status To fix this, this patch marks the pcm_get_format_name() as static, since it's anyway only used in tinypcminfo.c.

2014-09-24Defer filling enum-type mixers informationDavid.Coutherut
Currently, all information about all mixers are fetched during mixer_open(). For enum mixers, an additional step gets the string for each enumerated value - this can lead to a lot of ioctls and take time even when these mixers aren't used afterward. Defer fetching integer/string mapping values when needed (when getting/setting a enum mixer).

2014-09-09mixer: Add mixer_ctl_get_idRichard Fitzgerald
Add a function to get an id of a control that can be passed to mixer_get_ctl(). This can be used to lookup a control by name and store its id for later use rather than have the overhead of name lookup each time it is used. Lookup by id is quick and avoids the disadvantage that storing a pointer to the mixer_ctl object creates a client with a dependency on the address of the internal control array.

2014-08-18Revert "mixer: Control input value in mixer_ctl_set_value"Charles Keepax
This reverts commit 0e07647e4b9c52bb5f3766f9564ed38b6030e556. This commit disables reporting of an error when somebody requests an out of range value from a control which seems like a bad goal to start with, if something invalid is requested we should return an error not set things to the nearest valid state. Secondly since mixer_ctl_get_range_max returns an error for all control types except TYPE_INTEGER, all controls that are not integers will be set to -EINVAL with this patch included.

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.

2014-04-22Add 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>
