When I saw the file in logcat.log0, I suspect the following.

Hi YK,

Not similar, I used the same reproduce steps, but the CPU usage is low in Smart3.

After analysis, I think there is an infinite loop in logcat.log1. this will be root cause for high CPU usage.
I see the following logs being printed repeatedly.
2023-07-08 10:38:13.050000 29259 29259 30162 W audio-subMixingFactory "out_get_presentation_position_port(), pts not valid yet"
2023-07-08 10:38:13.050000 29259 29259 30162 I audio-subMixingFactory "WD1 threshold=6"
2023-07-08 10:38:13.050000 29259 29259 30162 W amlaudioMixer "mixer_get_presentation_position(), port not ready now

Please forward it to Amlogic for investigation.

Thanks,
Jason
