Description
Summary:
when playback using alc5682 codec on cometlake, there is a about 2s white noise when entering runtime suspend.
Test steps:
- Play some music, eg.
aplay -vv -Dhw:0,0 -c2 -d2 48California_Dreaming.wav - when it ends, check the runtime status
cat /sys/bus/pci/devices/0000:00:1f.3/power/runtime_status
The noise occurs when entering runtime suspended.
However, this noise only happens in suspending and if we trigger new playback, there will be no noise during playback.
Test env:
sof cml-001-drop-stable: 1f5a965
kernel topic/cros-sof-v4.19: f69d618
tplg: sof-cnl-rt5682.tplg
