[Realtek ALC887-VD, Pink Mic, Front] No autoswitch

[yesint]

Pulseaudio always sets "Line in" as input source after reboot or logout.
When plugged the microphone to front jack nothing happens, the microphone doesn't work.
After manual switching to "Front mic" in "sound settings" the microphone works perfectly, but its entry in the settings still shows "unplugged".
After reboot or logout the settings are lost and "Line in" is set active again.

This bug is annoing - one have to switch the mic mannualy every time I'm logging in. Less skilled users have huge troubles with this.

did your front audio panel support jack detection ?

your desktop have two capture devices and three input sources

how can pulseaudio auto switch the input sources when user plugged in line in and rear Jack at the same time ?

the codec can also be configured to select stereo mixer 0x0b as input by hint

In windows the jack is detected, so yes, it is supported.
I don't have anything at line in. The rear out is connected to speakers, but the rear in is empty. I don't understand your point.
Anyway in sound settings dialog ALL inputs are ALWAYS marked as unplugged regardless of what is connected to them.
I don't need auto detection that much, but I need it to remember preferences. If somebody could propose a workaround to make front mic a default and to save its volume between reboots that will solve my problem.

Status changed to 'Confirmed' because the bug affects multiple users.

[Raymond (superquad-vortex2)]

if your computer chassis do not have hda front audio panel and the front mic jack always return false

pulseaudio treat the front mic jack is not plugged

you need to disable the creation of jack detection control by set bit 8 of pin default
