** Description changed:

- Please refer to the following thread on Ubuntuforums.org about this issue:
- https://ubuntuforums.org/showthread.php?t=2494168
+ I did a fresh install of Mantic Minotaur on my MSI Prestige 14 Evo
+ laptop from 2020.
  
- Everything you need to know about the bug is documented there. The
- thread is 4 pages long.
+ In Ubuntu Settings, everything was working under Sound except for my
+ internal microphone. No sound was coming from it. Although, the input
+ device is detected.
  
- Thanks!
+ I checked alsamixer, under the correct sound card, and microphone was
+ muted, so I un-muted it. No change under Ubuntu Sound Settings.
+ 
+ I then made an edit to the following line on grub:
+ GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=1"
+ 
+ Then, I updated grub, and rebooted. Still, no sound from microphone.
+ Speakers were working still.
+ 
+ Added:
+ alias snd-card-0 snd-hda-intel
+ options snd-hda-intel model=auto
+ to alsa-base.conf, then rebooted, and now no input devices are being detected in Ubuntu Sound Settings.
+ 
+ Ran:
+ systemctl --user --now enable wireplumber.service
+ systemctl --user --now start wireplumber.service
+ 
+ and nothing changed.
+ 
+ Forgot to undo the changes made to grub, so I changed:
+ GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=1"
+ 
+ to:
+ GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
+ 
+ Updated grub, and rebooted the system.
+ 
+ Still, no input devices were detected in Sound Settings.
+ 
+ Experimenting, I removed the two lines appended to alsa-base.conf, and
+ ran sudo alsa force-reload. Then rebooted the system.
+ 
+ After I rebooted, the microphone was detected in Sound Settings, but
+ still no sound was coming from it. I couldn't hear myself talking into
+ it. Speakers were still working fine.
+ 
+ Out of curiosity, I again appended the two lines above to alsa-
+ base.conf, ran sudo alsa force-reload, and rebooted. After rebooting, no
+ input device was detected in Sound Settings.
+ 
+ Again, I removed the last two lines I appended to alsa-base.conf, and
+ ran sudo alsa force-reload, and rebooted. But after I rebooted, there
+ was still no input device detected in Sound Settings. But the speakers
+ are still working.
+ 
+ This is where I am currently. Someone mentioned to me that this is a
+ bug.

Title:
  No sound from microphone, and after adjusting alsa-base.conf, no input
  devices are detected

Status in alsa-tools package in Ubuntu:
  New

Bug description:
  I did a fresh install of Mantic Minotaur on my MSI Prestige 14 Evo
  laptop from 2020.

  In Ubuntu Settings, everything was working under Sound except for my
  internal microphone. No sound was coming from it. Although, the input
  device is detected.

  I checked alsamixer, under the correct sound card, and microphone was
  muted, so I un-muted it. No change under Ubuntu Sound Settings.

  I then made an edit to the following line on grub:
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=1"

  Then, I updated grub, and rebooted. Still, no sound from microphone.
  Speakers were working still.

  Added:
  alias snd-card-0 snd-hda-intel
  options snd-hda-intel model=auto
  to alsa-base.conf, then rebooted, and now no input devices are being detected in Ubuntu Sound Settings.

  Ran:
  systemctl --user --now enable wireplumber.service
  systemctl --user --now start wireplumber.service

  and nothing changed.

  Forgot to undo the changes made to grub, so I changed:
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=1"

  to:
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

  Updated grub, and rebooted the system.

  Still, no input devices were detected in Sound Settings.

  Experimenting, I removed the two lines appended to alsa-base.conf, and
  ran sudo alsa force-reload. Then rebooted the system.

  After I rebooted, the microphone was detected in Sound Settings, but
  still no sound was coming from it. I couldn't hear myself talking into
  it. Speakers were still working fine.

  Out of curiosity, I again appended the two lines above to alsa-
  base.conf, ran sudo alsa force-reload, and rebooted. After rebooting,
  no input device was detected in Sound Settings.

  Again, I removed the last two lines I appended to alsa-base.conf, and
  ran sudo alsa force-reload, and rebooted. But after I rebooted, there
  was still no input device detected in Sound Settings. But the speakers
  are still working.

  This is where I am currently. Someone mentioned to me that this is a
  bug.
