It is more complicated, but it works. Nevertheless, I have 2 problems:
- snd_pcm_hw_constraint_list() keeps a pointer to the list, so, it cannot be in the stack. It fix this with static struct and rate array.
- snd_pcm_hw_constraint_mask64() is not exported. Is there an other way to set constraints on the formats/sample widths?
