Ask Ubuntu Asked by solasaurus on December 29, 2021
I come here in desperation after reading many online posts and trying a few different ways to fix this problem.
I purchased a new HP – PAVILION 24-XA0070A and installed Ubuntu 19.10. Everything worked fine except no sound. I only got sound when plugging speakers into the headphone jack, but that has subsequently stopped working thanks to my tinkering.
Online forums indicate the most likely cause is that the HDMI sound modules are blocking access to the builtin speakers. My most recent tweak was to add the following to /etc/modprobe.d/blacklist.conf
# prevents speakers / analogue sound to work
blacklist snd_hda_codec_hdmi
It doesn’t seem to work, because I rebooted and when I did this:
lsmod | grep snd_
I got this:

Using pavucontrol I can see that the system can detect when I play audio. But nothing comes out of the speakers. I don’t need to use HDMI output in any form whatsoever, so I’m fine with switching these kernel modules off. My understanding is that the NVIDIA card has audio which the kernel recognises, but that this somehow blocks access to the builtin speakers for sound output.

Any help is appreciated.
I also had this problem after installing Ubuntu Studio 20.04 alongside Win10 on a refurbished HP Pro 6200 pc. I tried a few things from the answers to this question but that did not work. But I have sound now from the onboard audio by disabling auto mute in alsamixer with my scroll wheel. (view: all (F5) )
Answered by Rosarium Lane on December 29, 2021
I had the same problem, until about 10 mins ago...
I tried all the above under 19.10 on my HP Spectre x360, with a GEFORCE GTX installed. I could get Bluetooth to work - just - until a few days ago.
I am convinced this is an Ubuntu 19:10 issue on NVIDIA. I can dual boot this machine, so did so into W10. The system (using RealTek drivers) works fine but the default, out-of-the-box, Ubuntu 19:10 didn't. Recent updates appear to have managed to lose my Bluetooth devices.
Quite by chance, I found this itsfoss.com page
Having tried all their other tips I got to the last one which is intended for systems with 5.4 or less kernels ( I have 5.3.0-46-generic x86_64) ran:
sudo gedit /etc/modprobe.d/alsa-base.conf
then:
options snd-hda-intel dmic_detect=0
saved and closed the file, then shut down and re-started.
In line with Aerkusa's answer, I could now see my standard input and output devices. I configured things as that answer suggests and it works fine.

I have also had sound issues since upgrading to 19.10. Typically I can see all output devices, but no matter what I select there is no sound. Sometimes selecting and testing different outputs restores the sound. Until today rebooting always restored it. Sometimes this worked:
pulseaudio -k && sudo alsa force-reload
Today I noticed an update for alsa. Now after the update (including rebooting several times), I can still see all my output devices, but I get absolutely no sound on any of them. alsamixer shows 00 for all output devices and will not allow me to increase the volume. I can mute and unmute, but not increase. None of the old tricks have worked to restore sound.
I have two NVIDIA GPUs, an Onyx blackjack USB interface with a high end mic and headphone output, and a C922 Pro webcam that I sometimes use for input. The webcam mic seems to work fine for input. The Onyx input is no longer working, so there appear to be issues with both USB and HDMI audio devices.
Has anyone found a permanent solution to this? Is it best to just downgrade to last LTS? I had no problem with sound that version.

For me this bug started after the update to 5.3.0-42.34 kernel version.
The #3 answer in https://bugs.launchpad.net/ubuntu/+source/linux-oem-osp1/+bug/1864061 solved my problem :
This machine has dmic on it, so the legacy hda abort the probe: snd_hda_intel 0000:00:1f.3: Digital mics found on Skylake+ platform, aborting probe
And if want the legacy hda driver to work, please add options
snd-hda-intel dmic_detect=0in/etc/modprobe.d/alsa-base.confThis is a machine which has dmic on it, so please blacklist
snd_soc_skldriver through/etc/modprobe.d/blacklist.conf, then the sof driver will be loaded.And if there is some issue, I will fix it, I am working on the the sof driver for eoan kernel now.

Run this command:
pulseaudio -k && sudo alsa force-reload
After running this command I am able to see all output devices in the Settings menu & it solves the problem automatically.
This isn't a parmanent fix though.
I have GTX 970 on my desktop which provides display through HDMI port. Very often the output devices disappear from the option (& there is no sound) after I turn on the PC from suspension.

I had the same problem after an upgrade to 19.10
The symptoms were:
speaker-test -c 2 -D hw:1,0
worked (noise heard)
aplay gave no sound, but didn't show an error.
This helped:
I open the System Settings, went to
multimedia > loudness > advanced (3rd tab)
First I deactivated the HDMI device, then I set the second sound card to analog stereo duplex.
After that everything worked.
If that doesn't help get the alsa-info.sh from the alsa project on github to analyse the problem.
Answered by Lenoard08 on December 29, 2021
I had a somewhat similar issue. I found that after updating to 19.10, I was not getting audio from headphones. After not finding any issue in pulse audio or alsamixer, I found that setting the input device to be the same port as the output device resolved the issue for me.
In other words, if you're using the built-in speakers, set input device as built-in microphone, and if you're using built-in headphones, set built-in headset microphone (even if the headphones don't have a microphone).
I'm not knowledgeable enough about the kernel to guess why this has happened, but I hope my experience at least helps you troubleshoot further if it's not able to resolve your issue.
Answered by Aerkusa on December 29, 2021
I had a similar issue after upgrading from 18.04 to 19.10. In Settings it only shows a Test Output device and no real output devices.
It seems the drivers were loaded as with kernel 4.x. I found snd-hda-intel only dummy output after upgrade from ubuntu 18.04 to 18.10 which came to the conclusuion that timidity, a MIDI to WAV service was racing for the device.
I did this in a terminal:
sudo apt-get purge timidity timidity-daemon
This prompts you to confirm to remove timidity and timidity-daemon and if you do you should see real audio outputs in the settings after that if it is the same issue. If it was not you may reinstall with sudo apt-get install timidity
Answered by Sylwester on December 29, 2021
I'm having a similar issue. After some tests I check and the sound is working, the problem is somewhere width the volume. Using the 3.5 Jack ou built-in speaks, the volume is really too low, only in a silent space is possible to ear. Using sound throw HDMI ou Bluethoot (in my case earbuds) the sound works perfectly.
In my case I'm using Ubuntu 19.10 with 5.3.0-18-generic Kernel, I have the same problem width Ubuntu 18.04 after the last kernel upgrade.
Some extra info, I'm using a Lenovo Ideapad 530S
Answered by c42759 on December 29, 2021
You should go to Settings → Sound → Output → Output Device and try selecting a different output device (if you have not tried that already).
