We should be able to select the input, even with all the auto-detect goodness.

I need to manually switch back to rear mic every time that happens. Expected ======= I select the rear microphone as input (pavucontrol) and it stays that way. Workaround ========== I disabled this module in /etc/pulse/default.pa: # load-module module-switch-on-port-available and then restarting pulseaudio obviously solves this. Ideal workaround ============== Disable port switching for (selected?) input devices in pavucontrol. Or at least somehow honor my selection, e.g. if the input is marked as a fallback device, it shouldn't switch. Possible cause 1 ============= After pulseaudio startup, pactl shows these lines: analog-input-microphone-front: Front Microphone (priority 8500, available: yes) analog-input-microphone-rear: Rear Microphone (priority 8200, available: no) Note: I don't use the front mic port at all. Possible cause 2 ============= My sound card or ports may be creating noise that triggers "jack activation" events Possible cause 3 ============= Bios, hardware related issues trigger jack activation events.
