[Alsa-user] cannot get Capture capability on Interna Mic on hp2530p laptop

[<bar...@nt...>]

Hi,

Here cannot get Capture capability on Internal Mic on an old hp2530p elitebook laptop.

I have googled several days to find settings or a fix to get it working witjout success.
I also have tried some various options added to /etc/modprobe.d/alsa-base.conf also without success.

The internal mic actually works as I can hear from the internal microphone using as headset or the pc speaker when loopback is enabled in alsamixer.
The laptops users manual also tells the ability to use the lapppto for videoconference, which is my purpose using Zoom conference software.

Attached is the report of alsa-info.sh also here:
ALSA information is located at http://alsa-project.org/db/?f=778fd4d30e9d991e2893d5ab071c57e66065c0bc

Thanks a lot for any help.
Charlie
