I’m using a laptop currently and the problem is that there is no sound input at all. My earphones are fine. I can hear sounds from videos and calls just fine but my microphone isn’t working. It works on any other device except my laptop. I can’t figure out what’s wrong.
I tried a couple things. I tried changing kernels to no avail, and I’ve also tried to add a kernel option to the system by adding ‘options snd-intel-dspcfg dsp_driver=1’ to ‘etc/modprobe.d/alsa-hda.conf’. I am only using my earphones for sound input and so my laptop’s the built-in internal mic is basically useless.
Here’s the output of ‘pacmd list-sources’:

I also noticed that on pavucontrol, under Input Devices, the Headset Mic is unplugged even though I’ve plugged my earphones in. Is this normal?
I don’t know what to do. I’ve been trying to fix this since yesterday. Also, I am still a rookie linux user so if somebody could help me that would be great. Thanks in advance!
