Hi,

I was trying to figure out what exactly SNDRV_PCM_HW_PARAM_TICK_TIME does, but couldn't find too much.

Is it safe to say that nowadays this is unused and deprecated and the only reason it is kept around is for ABI reasons?

Right, it was a parameter nobody ever used. The corresponding API functions have been removed many years ago, but the parameter itself is kept for the compatibility reason.
