[Touch-packages] [Bug 1922715] Re: [Inspiron 5400 AIO, Realtek ALC274, Speaker, Internal] No sound at all (dummy output)

[Namo Amituofo]

Has exactly the same model (Dell Inspiron 24 5000 All-in-one, aka
Inspiron 5400 All-in-one). Also "aplay -l" showed the card is "ALC274
Analog". Finally got the sound working in Ubuntu 20.04, by appending the
following line

    𝚘𝚙𝚝𝚒𝚘𝚗𝚜 𝚜𝚗𝚍-𝚑𝚍𝚊-𝚒𝚗𝚝𝚎𝚕 𝚖𝚘𝚍𝚎𝚕=𝚍𝚎𝚕𝚕-𝚑𝚎𝚊𝚍𝚜𝚎𝚝-𝚖𝚞𝚕𝚝𝚒

in /etc/modprobe.d/alsa.conf. After reboot, the sound at both speaker
and microphone worked.

Various articles mentioned this. One such reference is:

A big thank you to the community!

Title:
  [Inspiron 5400 AIO, Realtek ALC274, Speaker, Internal] No sound at all
  (dummy output)

Status in pulseaudio package in Ubuntu:
  New

Bug description:
  Brand new PC (it is a descktop All-In-One with integrated speakers), no 
change to the bios, fresh install with no additional package.
  In the "sound" section of the parameters, the output menu has a single entry 
"dummy output" and the vu-meter below this menu tracks the input microphone, 
which works.
  (the UI is in Russian, it's a friend's PC, sorry if the English terms are not 
exactly right).
  Same with pavucontrol.
  Same on ubuntu 20.04 and 20.10.

  I first searched the internets and randomly tried the following additions to 
/etc/modprobe.d/alsa-base.conf (one by one), none of them worked
  options snd-hda-intel model=generic
  options snd-hda-intel model=alc274-dell-aio
  options snd-hda-intel model=auto
  options snd-hda-intel dmic_detect=0
  options snd-hda-intel index=2 # tested 0, 1, 2 and 8 -- wish I new what it 
means
  options snd-intel-dspcfg.dsp_drivers=1

  I was delighted to hear that Apport could play noise on this machine
  because before that I didn't get a click,  I was wondering if the HW
  was working.

  That's all. Bug reports are love letters.
