new 22.04 install cannot play sound on speakers

Question

I have a fresh install of Ubuntu 22.04. The Bang & Olufsen speakers aren't playing sound.

I've gone through https://help.ubuntu.com/stable/ubuntu-help/sound-nosound.html.en but nothing there helps.

I can get sound on headphones, but when I pull the headphones out, the sound is gone, even though the volume is set to max.

Speaker - sof-hda-dsp shows in the settings as being recognized, but it's not being used. When I pull the headphones out, the Output device switches.

sudo lspci -v gives:

    Subsystem: Hewlett-Packard Company Device 8bdd

    Kernel driver in use: sof-audio-pci-intel-tgl
    Kernel modules: snd_hda_intel, snd_sof_pci_intel_tgl

Similarly, I have an older laptop with a nearly identical setup, that actually works:

lspci -v | fgrep -m1 -A19 '00:1f.3'

gives

   00:1f.3 Multimedia audio controller: Intel Corporation Comet Lake PCH-LP cAVS

    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel, snd_sof_pci_intel_cnl

Perhaps switching the kernel driver in use is the key? How can I do that, if it will help?

Sound card not detecting and the command sudo apt-get install build-essential linux-headers-uname -r alsa-base alsa-firmware-loaders alsa-oss alsa-source alsa-tools alsa-tools-gui alsa-utils alsamixergui didn't fix the problem.

How to install Bang and Olufsen Audio drivers for HP laptop? failed to solve my problem.

No sound on headphones with sof-hda-dsp audio on ubuntu (and variants) also failed.

Audio output doesn't switch when headphones connect or disconnect didn't help either.

Ubuntu 20.04 - No sound also failed

cat /proc/asound/cards produces the following output:

 0 [sofhdadsp      ]: sof-hda-dsp - sof-hda-dsp
                      HP-HPEnvyLaptop17_cw0xxx-Type1ProductConfigId-8BDD
sudo gedit /etc/modprobe.d/alsa-base.conf

and add

options snd-hda-intel model=generic

as suggested Ubuntu 20.04 - No sound also failed.

using sof-bin as suggested by Sound card not detected - Ubuntu 20.04 - sof-audio-pci also failed.

I'm also getting

[    0.475866] pci 0000:00:07.0: DPC: RP PIO log size 0 is invalid
[    0.476486] pci 0000:00:07.2: DPC: RP PIO log size 0 is invalid

during the boot process. Is this connected to why my speakers don't work?

I have done the standard sudo apt update && sudo apt upgrade to no avail, as well.

when I grep for audio within dmesg:

I have also tried adding snd-intel-dspcfg.dsp_driver=1 to /boot/grub/grub.cfg but that changed nothing https://bbs.archlinux.org/viewtopic.php?id=275737

cat /proc/asound/cards gives the output:

                      HP-HPEnvyLaptop17_cw0xxx-Type1ProductConfigId-8BDD

sudo aplay -l

gives the output:

How can I get the sound working on my speakers?

Answer 1

It turns out that this a well-known problem with no easy fix, yet. See here for details. The laptop in question in that post is a HP ENVY x360 15-ey0xxx, which also uses Bang & Olufsen speakers. This Q&A post is quite active, with the latest reply as of this writing dated yesterday (July 25th, 2023). I did some digging through it, and it seems that you have two options:

1. Update your Linux kernel version to 6.3.2 as indicated by this reply. To do so, you can follow the instructions here. However, as explained in these answers, it is not recommended. Therefore, you may want to install a non-LTS version of Ubuntu instead, such as 23.04 or 23.10 when it comes out.
2. As indicated in this reply, you can install a DKMS module that fixes the problem by following the instructions here. However, for this option, it is extremely important to note the following warning under the reply:

Thanks for the patch, but note that this change can't be taken.
It's dangerous and may burn speakers on other machines that don't use
this configuration.
For now, those info relies on the BIOS ACPI setup with _DSD entry, and
vendors should fix it with BIOS updates.
There have been already discussions how to deal with vendors who don't
cooperate well.

I think both of these options are not ideal, and I would personally wait until this problem is fixed in a future release of Ubuntu.
