The speaker on your machine is recognized by analog-output-speaker-always, and the available is no.

need some pulseaudio log to debug.

usually, it should be analog-output-speaker.

That log doesn't contain useful info

Please edit /usr/lib/systemd/user/pulseaudio.service
comment the line of ExecStart,
and copy a new line of ExecStart, and add -vvvv and --target=file:/tmp/pulseaudio.log

reboot then upload the /tmp/pulseaudio.log.

Hui Wang, I'm not sure what you mean by :"comment the line of ExecStart,
and copy a new line of ExecStart, and add -vvvv and --target=file:/tmp/pulseaudio.log"

Could you made it more clear? What do you mean by " copy a new line of ExecStart "? You mean copy the same line I commented and add "-vvvv and --target=file:/tmp/pulseaudio.log" ? If not, what do you mean by " a new line of ExecStart" ? If you could just send exactly what I should write so it doesn't cause any more delay in sending you the information you need, that would be great.

@george,

#ExecStart=/usr/bin/pulseaudio --daemonize=no --log-target=journal
ExecStart=/usr/bin/pulseaudio -vvvv --log-target=file:/tmp/pulseaudio.log

reboot
then upload the /tmp/pulseaudio.log

pulseverbose.log Edit (2.5 KiB, text/plain)

I did that but there isn't /tmp folder containing pulseaudio.log. There is a tmp folder but it does not contain any pulseaudio.log. The only file related to pulse is pulseverbose.log in the home folder. If that file can help at all, I'm attaching it to these comment. Otherwise, I keep waiting for further instructions.

You should put the change into this file: /usr/lib/systemd/user/pulseaudio.service

If it doesn't work, please upload your /usr/lib/systemd/user/pulseaudio.service

I have attached my pulseaudio.log from the tmp folder after commenting and adding that code in pulseaudio.service.

Please see if it can be of any help.

Hello!
As posted before on this tracking bug (probably the wrong place) https://bugs.launchpad.net/ubuntu/+source/linux-5.4/+bug/1864871, I have the same issue with an old Toshiba Satellite L450 laptop.
I ran the live Ubuntu 20.04 image and the sound was recognized and played well.
In Settings I could see the output Internal speakers.
Then I installed from within the live image Ubuntu and still have sound.
Back then the kernel was 5.4.0-28.32-generic 5.4.30.
I've updated Ubuntu last night and surprise. Now I only have Dummy output (no sound).
I've researched and tested a lot of tricks to make it play but with no luck.
Attached is the pulse audio log file as instructed by @Hui Wang (hui.wang) in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875252/comments/5.

OK, it is highly possible that this is a regression introduced by the fix of https://bugs.launchpad.net/oem-priority/+bug/1869819

We will fix it in the ubuntu pulseaudio.

Awaiting anxiously for the update/fix. Do let us know once it is out, so that we can get back to you with the feedback.

Yes, it could be the regression of the fix of 1869819. There are two audio jacks and an internal microphone in my laptop, as said in that bug.

1869819 affects at least only two people; however, its regression/SRU affects many, Dell puters in particular!

Hello.
Ubuntu just updated pulseaudio from official channels and now I have sound.
Just a thought for newbies.... Even though after update computer doe not require reboot, in order to have you sound initialized please reboot.
That's what i did and now works.
Thank you guys.

@Bogdan(elrohe), how did you do it ? Mine still has the same problem and the sofware updater doesn't show any update pending. Did you install anything manually from anywhere ? If yes, could you share what you've done in details, please ?

@Bodgan (elrohe)

Please don't hijack this thread. We already are in pain for the past more than a fortnight. Yours is a different make of computer and hardware, and hence a different problem.

After listening to you, I updated, uninstalled/reinstalled alsabase, pulseaudio, pavucontrol, rebooted, only to find that I am back to zero with dummy output, with all these efforts going in vain and of no use.

So without knowing your problem perfectly and without even knowing what has been written by others in the thread and without knowing what is the issue at hand in the thread, please don't hijack into others' thread or throng every bug report on the Launch Pad, where N audio problem has been reported, with your issue and findings. Open up a separate bug report with your issues and wait for the team to look at it and respond.

Hope you take it in the right spirits.

@George (georgewf)

Bodgan's puter is a Toshiba Satellite, hence different hardware and different set of drivers. So it's an entirely different issue.

Ours is a Dell with an Intel soundcard. The problem still remains in our puters due to the regression of fixing up another bug elsewhere here: https://bugs.launchpad.net/oem-priority/+bug/1869819

They are urgently working on it.

@Rajasekharan N (rajasekharan)

The link you've posted to another bug https://bugs.launchpad.net/oem-priority/+bug/1869819 actually did the trick and helped me bring back my sound card.
It was the patch that @hugh chao released on his channel as seen in this link
https://code.launchpad.net/~hugh712/ubuntu/+source/pulseaudio/+git/pulseaudio/+ref/focal-1869819.

@George (georgewf) There is a new update available for PulseAudio. Don't go for it. It again breaks the settings, and the internal speakers are shown as Dummy Output again.

I have reported the bug again. (bug 1878327)

Well to late.
My laptop already updated.
Never got the chance to see what was the update about.
Just requested to restart.
I'll follow the bug you reported.

Oops. I couldn't save you the trouble. Sorry. It didn't strike me for about 12 hours or so since the update to alert the remaining affected people. During this time, after realizing that Pulseaudio has broken down again, I was trying if I can do with Alsa alone or if I could find any other alternative for Pulseaudio. However, I was unsuccessful.

It's nearing a month since I ran into this trouble by updating to 20.04 LTS and have run wall to post.

There is hope. There is a new fix/update coming. It's already in the git. I don't know when it will be available in the updates channel.

See bug 1876065 for the latest info regarding this.

Don't worry. It's a good thing that each problem risen from linux will teach me more about it as I am a newbie :)
Thank you though for the heads up regarding the fix.
I'll be waiting for the official release.

The current version is pulseaudio 1:13.99.1-1ubuntu3.2.

There is a fix/patch (Version: pulseaudio 1:13.99.1-1ubuntu3.2lp1869819) in this PPA that you can use it for now until the next update/release:

This patch didn't fix my built-in speaker and microphone.

@Alexander (klimat-88)

The fix is for HDA Intel soundcard built-in audio. Couldn't find what is your soundcard from your bug report. Wait for the coders to respond to your bug report.

As far as I know, you may try undoing all these: "options snd-hda-intel dmic_detect=0" to /etc/modprobe.d/alsa-base.con, add "blacklist snd_soc_skl"

And then apply the patch.

Or uninstall and reinstall PulseAudio. Then enable "Pre-released updates (focal-proposed)" under the tab 'Developer Options' in Software & Updates. Then update the cache before closing Software & Updates.

Open Software Updater, fetch and apply updates. Reboot.

Try if the audio works now.

For the rest of the affected souls here:

The patch that I mentioned above has now been incorporated into the Focal proposed updates. To fetch it to your system before it is released in the stable channel, do the following:

Enable "Pre-released updates (focal-proposed)" under the tab 'Developer Options' in Software & Updates. Then update the cache before closing Software & Updates.

Open Software Updater, fetch, and apply the PulseAudio/dependencies updates (pulseaudio 1:13.99.1-1ubuntu3.3). Reboot.

The audio should be working fine now.

Voila.

The patch did not resolve the issue for me, and the bug is still there. I just upgraded from 18.04 to 20.04 on a Dell Latitude E6230, and there was no sound output, with the sound settings showing only 'Dummy output'.

I had to do a fresh reinstall of 18.04 which was extremely time-consuming.

The same problem had occurred for me in the summer on a Dell Latitude E7270. I saw then that there were lots of reports of the problem, and it seems inexplicable to me that this has not been fixed.

I guess I'll have to start looking for a different Linux distro.
