[alsa-devel] Support for floating point controls?

Greetings,

some of our products now have control paramters that are 32 bit floating point values.

I wonder if a patch implementing float ctl elements would be accepted? Note that the floats are not manipulated in the kernel at all, the values are just passed through from the hardware to userspace (?)

Adding something like:

#define SNDRV_CTL_ELEM_TYPE_FLOAT ((__force snd_ctl_elem_type_t) 7)

struct snd_ctl_elem_info { ... union { struct { float min; /* R: minimum value */ float max; /* R: maximum value */ float step; /* R: step (0 variable) */ } float; ... }

struct snd_ctl_elem_value { union { union { float value[128]; } float;
