[Solved] No sound on Meteor-Lake hardware

[RonJ]

This is a continuation of a thread that was started to fix install issues on a new HP Envy laptop.If interested, you can see what was do so far here:
viewtopic.php?t=160837
I have upgraded to the latest bookworm/backports kernel 6.11.12 amd64 and have upgraded to Pipewire-Audio version 1.2.5-1~bpo12+1 also from backports. Still no sound.

Any help Please

[Shamak]

I bought my computer new a couple of years ago and it had sound problems. I believe my sound card company put out a patch and it was included in a more recent kernel than was in backports. @sunrat recommended using the Liquorix kernel which worked. I believe sunrat uses the Liquorix kernel. I may be completely reading it wrong but it may be at version 6.11.6 (see the last link).

Definitely wait until a more knowledgeable user comes along before installing it. I'm just a regular user and am not an expert.

https://liquorix.net/

https://github.com/zen-kernel/zen-kernel

[sunrat]

I've been using Liquorix kernel for years; it's better for audio production plus has other benefits like default zram. It runs performance governor by default also which can cause more heating, but easy to change that with cpupower config file.
I'm not sure the 6.11 kernel will build the Debian repo Nvidia driver. I'm staying with the last 6.10 Liquorix ( 6.10.9-1-liquorix-amd64) until a new driver appears.
Current latest is linux-image-6.11.6-1-liquorix-amd64 (if you don't have Nvidia GPU or possibly other needed DKMS modules). Worth a try for sure. It's easy to uninstall it if it doesn't work out.

[FreewheelinFrank]

Ok I have reinstalled everthing and system is working fine with wifi. Now on to the sound problem. Here is the output from the latest install. If you compare the output above (working sound on 12.7.0 Trixie) to the output from latest install below, the only difference in audio is the PulseAudio version witch is 16.1 in "trixe" and is Pipewire version 0.3.65 on latest install.

inxi does not tell you everything that is different between the two installs.

Trixie will also have updated ucm, topology and firmware files, which let the system know the way the parts of the sound system are organized or connected, without which the driver for the sound device will not work.

This information should be defined in the BIOS, but often manufactures omit it because the Windows drivers contain the information and they are not really interested in supporting Linux.

Hardware configuration fixes to get sound working are added in to the driver in the Linux kernel, but also to other files which supply information to the kernel - the files mentioned above.

The fact that sound is working in Trixie but not in Bookworm with an updated kernel suggests other files are missing.

Please post the output of the following command after a recent boot:

Code: Select all

# dmesg | grep "snd\|sof\|intel\|firmware"

This will give us any error messages from the kernel as it tries to load the sound system.

The missing files will not be in Backports unfortunately, but may be installable from Trixie, depending on current compatibility between Bookworm/Trixie, or from upstream. I need to update my page on this.

viewtopic.php?t=153813

Give us the dmesg output and we'll go from there.

Addendum:

You could also check for BIOS updates - see this link:

viewtopic.php?t=160856

[sunrat]

As a side note, the Stable version of inxi is quite old. A newer version (3.3.36-1-1~bpo12+1) is available in backports:

Code: Select all

apt install -t bookworm-backports inxi

It may provide better info.
You will also get better info by using the correct inxi command, inxi -Faz[ not inxi -FAZ

But as FreewheelinFrank suggests, your computer may just be too new for Bookworm.

Should be run as user too I think, not root.

Your system recognises the sound card and loads a driver, not sure if it's the right one.
Still no joy in aplay -l? Have you tried alsamixer (may need to install alsa-utils package) in a terminal, press F6 to select card then make sure volumes are up and not muted with M at the bottom of the sliders.

The driver is there but there is missing firmware. The Debian package pages were really slow when I looked earlier, but it looks like some of it is in the SOF firmware in Sid, which should be manually installable without issue, and there's another bit available from GitHub. I will have another look in the morning as I'm pooped now.

[stevepusser]

You probably need newer firmware-sof-signed, which I don't think is backported yet for Debian. Also, your graphics is not at its full potential, using swrast (software rendering instead of GPU), and llvmpipe.

A user got the same generation Intel hardware working out of the box by switching to the MX Linux AHS edition, so here's their graphics and audio:

You need at least a 6.8 kernel for Meteor Lake, according to Intel. MX AHS also has a backported Mesa, Nvidia and other DKMS drivers for 6.11 kernels living there, and the latest firmware backported from Sid. You can download the latest monthly MX AHS update, make a bootable USB with the ISO, and check to see if your hardware works in a Live session without installation. Bookworm-backports has a backported Mesa, too, but no firmware the last I looked--probably someone should suggest that on the mailing list.

You probably need newer firmware-sof-signed, which I don't think is backported yet for Debian.

firmware-sof-signed can be downloaded from Sid and installed manually, or the required files can be extracted to the appropriate location. I can't see any issue with doing this as it overwrites the firmware directories with newer ones.

In this case the firmware is sof-mtl.ri. packages.debian.org is still giving Service Unavailable, so I don't know if this is a file that has been added or updated.

[ 4.959310] sof-audio-pci-intel-mtl 0000:00:1f.3: firmware: failed to load intel/sof-ipc4/mtl/sof-mtl.ri (-2)
[ 4.959312] sof-audio-pci-intel-mtl 0000:00:1f.3: SOF firmware and/or topology file not found.

There is also this

[ 1.439352] i915 0000:00:02.0: [drm] *ERROR* GT0: GuC firmware i915/mtl_guc_70.bin: fetch failed -ENOENT

It is indeed available at the link in the output:

https://git.kernel.org/pub/scm/linux/ke ... guc_70.bin

Not sure if it has anything to do with sound.

@RonJ

MX Linux AHS edition as stevepusser suggests would be an excellent option. If you want to try and get sound working in Bookworm, you could download firmware-sof-signed from Sid and install it manually. Do not add the Sid repository, as you do not want to upgrade anything else to Sid. Just download the package (when the servers are working again) and install it locally. There is no guarantee that this will work, as SOF may also need updated alsa-ucm-conf, which may not be installable in this way. In which case I would definitely go with MX.

There is also the mtl_guc_70.bin (video?) firmware above. Download this and move it to the location in the link.

[sunrat]

Here's a link to the most recent firmware which was updated a month ago - http://ftp.us.debian.org/debian/pool/no ... -2_all.deb . It contains sof-mtl.ri

[RonJ]

BINGO
I have sound. I downloaded the and installed:

Code: Select all

 firmware-sof-signed_2024.06-2_all.deb 

and after reboot sound is working.
Thank you all, I can not begin to tell you what it means to have this kind of support. All of you make Debian what it is, Great!

[arzgi]

Very nice you found the solution and also told what you did.

Can you please edit the header of your first post in the thread, and add [SOLVED] to front of it. So anyone browsing the forums sees no furthter acitviecs are needed, and perhpas some one with same kind of problem sees possible solution.

[stevepusser]

Don't forget about getting the graphics working fully--upgrade to Mesa 24.2.4 from backports along with firmware-intel-graphics there: https://packages.debian.org/source/book ... re-nonfree
