A critical side-effect was observed along with the commit 62d5ae4cafb7
("ASoC: max98090: save and restore SHDN when changing sensitive registers").
When keep playing something,
(e.g. sox -n -t s16 -r 48000 -c 2 - synth sine 440 vol 0.1 | \
aplay -D hw:0,0 -f S16_LE -r 48000 -c 2)
the recorded sound has chance to break (clipping).
(e.g. while [ 1 ]; do
arecord -q -f S16_LE -d 2 -r 48000 -c 2 test.raw \
sox -t s16 -r 48000 -c 2 test.raw -n stat \
...
done)
The series reverts all related commits.
I feel really sorry for the whole mess.
