avail increment at 8 frames which is less than min period size 16 and period
size 1024

this mean some tsched feature are supported

hwbuf_unused can be set to non zero (e.g. multiple of 8 frames instead of
period size)


min_period_size: 16 frames, dir: 0
Playback hwparams: FIFO size is 0
Hardware PCM card 0 'CA0106' device 0 subdevice 0
