Hello I am having a weird problem, i say weird because of my lack of technical experience.
my Lenovo-Thinkpad T450 runs Ubuntu 23.04 (Lunar Lobster). usually the F4 key on this machine will handel muting/unmuting the Microphone, the thing is before I log into my user account on the login interface when I press F4 is working properly, after logging in the key does not work anymore and in Settings -> Sounds shows no input device. i created a new user and when I log into that new user every thing is working properly.
so from here I don't know where to start debugging this, I would really appreciate it if someone has knowledge and could help me in debugging this issue and maybe find a solution.
what I found on internet to debug the issue:
User[no-input]$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: PCH [HDA Intel PCH], device 0: ALC3232 Analog [ALC3232 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
User[no-input]$ cat /proc/asound/card*/codec* | grep Codec
Codec: Intel Broadwell HDMI
Codec: Realtek ALC3232
then i went here and tried to find a module to edit /etc/modprobe.d/alsa-base.conf and from the modules i thought they should work for my machine nothing seemed to do any positive change
checking dmesg for loaded input devices after booting up
User[no-input]$ sudo dmesg -wH

from the above I guess this is why the button is working before logging in, I am not able to find whats happening after logging in
