I know, this question has been asked a hundred times before. I have tried all of those hundred solutions and nothing works.

I have a fresh install of Ubuntu 20.04. All I had was 'Dummy Output'. I have done a fresh install of 22.04, same issue. I have upgraded from 20.04, same issue. After installing/uninstalling/editing etc I now have an HDMI/Display port as an option in sound. I have no Display monitor. Reverted to 20.04 to start again. I have HDMI and Dummy only, no analogue, and no way of listening to anything without HDMI speakers.

No option for analogue sound and a laptop without sound is going in the bin.

I am not technically minded - I use Ubuntu because it works (usually)

OK. If anyone is willing to walk me through this I would appreciate it. I use an IOTA Flo360. Ubuntu 20.04 (but can reinstall with 22.04?? ((rather not, has caused problems on two old machines ((wifi adapter disappeared/display was upside down)) )

A bit vague, I know. Anything you need to know, then ask. If you need info from the terminal then please give me the code to cut and paste. I have used Ubuntu for 10+ years but I have rarely needed to understand anything pre-20.04. It just worked (restricted extras codecs aside) Since 20.04 LTS I have had to spend a week or so on every machine to render them usable.

  • Without 22.04/23.10, I can only suggest exploring hdajackretask. Please also provide details about your sound card, perhaps from lspci and aplay -l – Daniel T Feb 28 '24 at 22:25
  • lspci Multimedia audio controller: Intel Corporation Device 3198 (rev 06) – Kelv FT Feb 29 '24 at 13:20
  • Not sure that was readable. I will try again. lspci

    Multimedia audio controller: Intel Corporation Device 3198 (rev 06) and aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 3: Generic Digital [Generic Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 Hope that helps, thanks for getting back to me.

  • hdajackretask says I have an Intel Generic codec and HDMI outputs only. – Kelv FT Feb 29 '24 at 13:32
  • Have you tried https://askubuntu.com/a/1235880/1004020 and https://askubuntu.com/a/1295435/1004020 ? – Daniel T Feb 29 '24 at 13:40
  • Thanks, I will try them now – Kelv FT Feb 29 '24 at 13:46
  • I tried everything on the first link, a few times now. I have different kernels but I did give it a try. No difference. I couldn't make head nor tail of the second link, I'm afraid I have no idea how to edit as suggested, I'm a copy and paste guy. I can copy what is suggested but I don't know where to paste it or even how. Cheers again. Kelv – Kelv FT Feb 29 '24 at 14:03
  • So basically open the file with sudo vim /etc/modprobe.d/alsa-base.conf , and paste options snd-hda-intel dmic_detect=0 then options snd-intel-dspcfg dsp_driver=1. Remove other lines with the same name if you already added any. This does the same thing as the grub option. Fully apply the settings with sudo update-initramfs -u and reboot – Daniel T Feb 29 '24 at 14:27
  • Result from Terminal sudo vim /etc/modprobe.d/alsa-base.conf [sudo] password for ft: sudo: vim: command not found – Kelv FT Feb 29 '24 at 14:33
  • Replace vim with nano or another command-line text editor or install it. – Daniel T Feb 29 '24 at 14:37
  • Cheers, managed it with Nano. Same result though, still only hdmi audio. – Kelv FT Feb 29 '24 at 15:17
  • So ... currently doing a live install of Ubuntu 23.10.1, just checking it out. I have my sound card back - Celeron/Pentium Silver Processor High Definition Audio - One problem remains; the volume level, even at maximum is so low as to be inaudible. Any ideas on this one? Thanks people. ETA - headphones work - low volume but they work. – Kelv FT Feb 29 '24 at 19:07
  • You can use pavucontrol to set the volume to 200%. Are you sure it's set as speaker and not line out? – Daniel T Feb 29 '24 at 19:13
  • Not sure, no. It's kind of a moot point anyway as the LiveUSB does not give me an option to install. It just boots into a live USB. Am trying a fresh fresh 22.04. now. Thank you Daniel, I am gonna let you be for a bit, thanks for your help. – Kelv FT Feb 29 '24 at 20:50
  • Okay, well I think my computer had died. 22.04 couldn't load as my keyboard and mouse stopped working. Managed to install 20.04 again, but the mouse and keyboard stop after a minute or so. I am going to see if I can re-install my windows. Thanks for the help. – Kelv FT Mar 01 '24 at 14:22
  • Okay,, running windows again. It is working. I will never put a linux OS on a machine again - unless it is a laptop that no longer works. Post 18.04 Linux is a risk. Thanks again. I may try when the 24.04LTS comes out. – Kelv FT Mar 01 '24 at 19:47
