I had fedora 32 installed and the internal microphone worked well all the time.
But, after updating to fedora 33 I haven’t been able to make it work, in the Gnome settings the device is recognized but it does not catch any sound.
When I plug a earphone the microphone of it does work.
This is the output of arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: Generic_1 [HD-Audio Generic], device 0: ALC257 Analog [ALC257 Analog]

Hi, I solved with:
1.-
sudo nano /etc/modprobe.d/blacklist-local.conf
then inside paste:
2.-
blacklist snd-soc-dmic
blacklist snd-acp3x-rn
blacklist snd-acp3x-pdm-dma
close(crtl+x) and save(y).
3.-reboot
after that work mic and speaker:

Hi, @mamaldonadov , welcome to this forum and thanks. This indeed works.
However, it’s only a workaround of course. I came here from this thread and already opened a bug report here .
Can you explain why that happens/link a bug report or so one can follow, so we can see when there will be a “real” fix of this bug?

I have reported my case in the same bug report as you, but I don’t know why it happens.
Maybe @mamaldonadov , would you help us with this please?

Yeah, I reported it as a pulseaudio bug. Also don’t know yet whether it is really a bug in pulseaudio or the kernel or so.
Also i do have a possibly related bug: Even when I use Bluetooth headsets now, the microphone never works, regardless of which codec I choose.

Still waiting for some reply in the bug report , so I’ve now assigned it to the kernel component in the hope more people read there…
Also anyone got a solution for external microphones ? As said, the internal one works now, but external (Bluetooth) do not. As said:
Maybe also this thread can help, but it’s about Fedora 31, so really oldish…

There is progress and it seems to be some AMD issue.
Also one does not need to blacklist the whole module. A simpler workaround is in:

However, also opened a bug report for the Bluetooth headset now:

Here is how that looks like:
