            Bug ID: 264207
           Summary: No sound input on the headset jack, ALC292.
           Product: Base System
           Version: 13.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: alexlapugeanfbsd@outlook.com

Hello,

I have two Dell laptops with a 4 pin headset jack (Dell E6440 and Dell E6540).
Jack sensing detects the headset speakers but not the headset microphone, the
headset microphone is not working.

I tried to change sources in the mixer but to no avail.

In linux, the headset microphone is associated with NID 0x1a (26), and the
entire headset works without issues.

In FreeBSD, NID26 is marked as a SPEAKER even though it's not, I changed it
thru device hints to Mic.

The last issue is white noise in the headset speakers whenever the igain for
the onboard microphone  (NID18) is not 0, even setting it to just 1 starts the
white noise again.


cat /boot/device.hints
hint.hdac.1.cad0.nid18.config="as=3"
hint.hdac.1.cad0.nid22.config="as=0"
hint.hdac.1.cad0.nid25.config="as=0"
hint.hdac.1.cad0.nid26.config="as=4 device=Mic conn=Jack"
hint.hdac.0.cad0.nid6.config="as=0"
hint.hdac.0.cad0.nid7.config="as=0"
