Sometimes, there is a scratchy tenth of a second (in handsfree and headset),
If you set CONFIG_CPU_IDLE=n, do you still have the scratchy sound? Or with 4.19 kernel if you can cross check it?
If it is not there w/o CPU_IDLE then can you try one thing: print out the latency usec the patch is calculating and, by guess divide it by 10 and pass that to pm_qos API. My calculation of the usec is not correct or I'm calculating it in a wrong way?
