[pulseaudio-discuss] Hiccups in audio

[pl bossart]

You probably want to use an interrupt-driven mode rather than the
timer-based scheduling if the driver uses internal memories available
in i.MX; you would not have a precise idea of the DMA read position.
Try loadind the alsa-sink module with tsched=0
