We have a OEM bug #1727951, in this bug, The Dell OptiPlex 7460 AIO can't
detect external mic and can't record sound via external mic. After applying
the fixup of ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, the problem can be fixed.
And oem project is waiting for this patch to be merged into linux-oem asap.
The patch is only for artful/oem-kernel since the oem project is waiting
for this patch. Bionic kernel is a stable kernel in mainline, and this patch
is also sent to stable mailist, so it will be merged to bionic kernel
sooner or later.
plug the headset and record the sound on this machine, we can see the
external mic in the sound-setting and can record sound through this mic.
one commit from mainline kernel.
very low, since this patch only applies to specific Dell machines which have
