2016-03-05include time.h, to prevent use of struct timespec before definitionDima Krasner
In some old (2.6.32.x) kernel headers, asound.h does not include linux time.h when __KERNEL__ is undefined, which may break userspace. The build failures caused by this are similar to those fixed by c8333f8c. Signed-off-by: Dima Krasner <dima@dimakrasner.com>

mixer: remove separate info list
2015-10-20mixer: remove separate info listRichard Fitzgerald
Each mixer_ctl has an associated snd_ctl_elem_info, which was kept in a separate array with pointers from the mixer_ctl to its corresponding snd_ctl_elem_info. This means double pointer dereferences when looking up the info. It also means extra work to add support for extending the arrays to include dynamically added controls because the pointers from the ctl array to the info array would have to be updated. This patch removes the info list and gives each mixer_ctl struct its own local snd_ctl_elem_info, removing the additional pointer dereferencing.

tinypcminfo: make function pcm_get_format_name() static
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.
