Hello,Mirone, my audio card is CX20751/2, speaker is working but both internal and external mic are not, can not detect the input level, could you take a look to see anything is wrong.And cx20751/2 is very similar to cx20753/4 which can use the int mic.View attachment AppleHDA-274.7-CX20751-2.zipView attachment codec.txt.zip

need to do a better investigation, conexant codecs mostly does not have an Audio Mixer, and ranging from revision to revision There are big differences, I'm going to be busy in the next few days, so I should look for that this weekend.

Hi I have this codec on my UX303 and ran into the problem of the mics not working full stop.

Ive had some luck getting all audio to work on my laptop using both VoodooHDA and AppleHDA. Until Mirone or another indiviudal can find a way to get AppleHDA working fully for this conexant codec do please take a look!

Your comment does not match the data:
// 0x19 SET_PIN_WIDGET_CONTROL 0x25
"Command", Buffer() { 0x01, 0x97, 0x07, 0x24 },

What is the actual intention?
Keep in mind the verbs are only sent at init/sleep/wake (as per your config).
When do you actually need to send them?

And... no "Problem Reporting" files attached.
