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.

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.

When user want to set a mixer control with a value out of range,
the mixer control will be set at its maximum
|
|
|
|
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.
|
|
This replaces (and extends) the existing get/set_bytes
API, which is no longer required.
|
|
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.

Just like the pcm_get_error() API, simplify the mixer API
functions to return pointers to constant strings instead
of making copies of strings.
|
|
Use existing routines to read BYTE controls. Somewhat inefficient
since an ioctl is done for every byte, some caching in intermediate
fields would be beneficial.
|
|
Remove the use of the errno variable and instead return errors
directly where appropriate.

- re-add function to set enum type by string
- implement setting of mixer values in tinymix
- fix bug: read current mixer values before writing
|
|
- 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
|
|
- 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
