Hello dear all, first of all let me tell you that i am quite new using linux. I installed pop os, and i found it really awesome.

However, when i tried to have a video call the input audio (mic) do not work at all.

Output audio works but no input.

So i already tried several options like pulseaudio, changing the alsa config and so on, but still the same.

I DONT KNOW IF I AM DOING SOMETHING WRONG AND THE SOLUTION CAN BE REALLY SIMPLE. As i told you before i am new using linux.

I am looking for help

My computer is a desktop HP touchsmart 300 (i don't care about the touch i only need internal mic)

Thanks in advance
Alberto

Go to your Audio Mixer, then to "Input Devices". Does it list your internal microphone there?

Thanks for your reply.

Look, i searched for it and says something like "no input devices". I am sure my computer has internal mic because before i was using windows and the mic was fully working.

What else can i do?.
Thanks

Install inxi and then run it from the command-line and share the output.
Code:
inxi -Fxz

Which exact model of the "HP touchsmart 300" do you have?

According the hardware specifications it doesn't have audio input:

Well i am just wondering, why before when this computer had windows, i was using Skype zoom and some other apps (without headphones), and i was able to speak.

Is there a reason for it?

You could try updating your kernel to the mainline kernel to see if it detects it then. Since PopOS is based on Ubuntu you can just used the mainline tool described here. After it is installed just search for "mainline" in activities, open it, then it will take a while to load, then select the newest kernel(which is at the top), click install, then after it's done it will tell you. Then all you have to do is reboot, and then you can see if it recognizes you input audio device then. If it doesn't you can try different kernels until it recognizes it, it would help if you knew the exact hardware specifications of the input audio device of your internal mic. I hope that helps some ;)

Thank you very much

i already did it.

and i went to volume control "input device" choosing "all input devices" in 'show' field appears this (see attached file). the same happens changing to "monitors" in 'show' field
is that my actual mic?

BTW i found a website on which some posted the same situation than mine, also the computer belongs to hp and touchscreen 300.

so if that helps. Here goes the info

Code:
The speakers (and plugged earphones) on my HP Touchsmart 300 work fine. However, the mic doesn't work at all, neither the internal one nor a plugged one. In Windows the mic works as expected, but naturally it's very annoying to have to switch to Windows just for the sake of using Skype... I think this may be a bug in ALSA but I'm not 100% sure.

I'm using ALSA v1.0.24.2 and ubuntu natty with kernel 2.6.38-10-generic-pae. The last line of my /etc/modprobe.d/alsa-base.conf file is:

options snd-hda-intel model=touchsmart

although I have also tried unsuccessfully with:

options snd-hda-intel model=mobile
options snd-hda-intel model=laptop position_fix=1 enable=yes
options snd-hda-intel enable_msi=1
options snd-hda-intel model=auto position_fix=1 enable=yes

My sound card is, according to lspci:

That looks good since it's recognizing it now, that should be the internal audio input device. What kernel are you running now? Can you run inxi again and share the output?
Code:
inxi -Fxz
Does it work now?

Can you share the output of:
Code:
arecord -l
pacmd list-cards
We'll just start with this.
