After installing the Ubuntu Linux, the micmute led status is not correct. Users expect that the led is on if the capture is disabled, but with the current kernel, the led is off with the capture disabled.
We tried the old linux kernel like linux-4.15, there is no this issue. It looks like we introduced this issue when switching to the led_cdev.
The behavior can be controlled via "Mic Mute-LED Mode" enum kcontrol. Which value does it have now? If it's "Follow Capture", that's the correct behavior. OTOH, if it's "Follow Mute", the LED polarity is indeed wrong.
It is "Follow Mute", if I change it to "Follow Capture" manually, the led status becomes correct.
OK, thanks for confirmation. Applied now.
