Ubuntu 21.04 No sound on new Dell Inspiron 7700 AIO

Question

I just purchased a new Dell Inspiron 7700 AIO computer with 11th gen i7 CPU. Installed Ubuntu 21.04 and it mostly works ok. However, I have no sound from the built-in speakers, and the sound settings panel shows "Dummy Output" as the only output choice.

I've currently attached a bluetooth sound output device and am successfully using it for sound output, but I'd prefer to use the AIO's built-in speakers.

Any ideas on what I can check?

I found some information about Inspiron 7720 (not 7700), whose NVidia stereo controller is also not supported in any kernel versions up to 5.14. https://linux-hardware.org/?probe=f3b0e7fa47 — Archisman Panigrahi, Sep 26 '21 at 14:44
@ArchismanPanigrahi Thanks for the research! I do have a Nvidia MX330... and it's giving me some grief... so I wonder which audio controller is being used... — heynnema, Sep 26 '21 at 15:07
snd-hda-intel was often blacklisted in the past because there was a time when video cards' sound devices were conflicting with other sound card/devices -- in other words, it was stealing sound device '0' which many of us didn't want. Fastforward to now when most people actually are using the on-video or on-board sound devices intel makes for dell opti-series, we have a problem of it being blacklisted. You can quickfix this with a "sudo modprobe snd_hda_intel" and a "sudo alsactl force-reload' but you still need to remove the blacklisted module in /etc/modprobe.d (which file varies) — osirisgothra, Aug 13 '23 at 21:15

The fix was to add the following to /etc/modprobe.d/alsa-base.conf and reboot...

# Enable internal audio and headphone jack on Dell Inspiron 27 7700 AIO
options snd-hda-intel model=dell-headset-multi

How did you find it? – Archisman Panigrahi Oct 05 '21 at 14:01

@ArchismanPanigrahi I went Googling for the Realtek ALC3289 audio controller, and buried deep in the responses, was the fix. There were a few hits, and I should have noted the sources in my answer... but I was too excited over the fix :-) Found one of them... https://askubuntu.com/questions/1258583/install-realtek-audio-drivers-in-ubuntu-20-04-intel-nuc-nuc10i7fnh – heynnema Oct 05 '21 at 15:17
