Hello,
Any luck with this? I am also struggling to get the internal
mic to work on the X1 Carbon 7th Gen. Have gone through
everything discussed here, but still no luck.
My dmesg and mixerctl match those already shared in thread.
Happy to share anything else that might be helpful, but after
reading through the multimedia FAQ and this thread I am
not quite sure where to go next.
Best,
Zachary
