After kernel rebuilt and reboot still recieving same result

rebuilding what, how, and why? What is the output from?

My guess is the hardware is too shiny new (out in the wild for only a number of months(?), and is $$$), and no one has figured this all out yet. LLMs still may be lagging behind in terms of up-to-date Linux things.

May need to check out a bleeding edge, more ultra-current distro (aka Arch-like or other rolling style) as it may fare better with current kernels, firmware, Alsa, UCMs, etc.

I did a Kernel-table modification on soc-acpi-intel-ptl-match.c to make the PTL match my MSI laptop. I did several edits and rebuilt via make -j$(nproc) M=sound/soc/intel/common and sudo cp sound/soc/intel/common/snd-soc-acpi-intel-match.ko \
$(modinfo -n snd_soc_acpi_intel_match)

sudo depmod -a

The hardware is definatly too shiny but was hoping maybe the group could put it on their radar and provide a fix.

I don't want to go with another distro of linux due to me specifically using the 24.04 of Kubuntu since it is optimized for Pixinsight. I do alot of astrophotography in my spare time.

That's too deep for this old fart.

You more likely need a more current kernel version as well as support stuff. With SOF audio, iirc the UCM files are important, too. And the firmware probably needs updating as well.
Trying a live version of an up to date Arch based distro is an easy way to check if that alone gets your audio working, and might point to what you need.

You can get newer kernels in *buntu, but the rest of the Audio stack I do not know.

I would reinstall 26.04 so you are back to 'stock' without the kernel mucking. Then review the following Google AI answer.

Because this issue persists across Fedora 44, Kubuntu 26.04, and Kubuntu 24.04, the problem is not a simple configuration bug. It is a known hardware integration issue where the Linux kernel fails to map the internal amplifier pins (usually Realtek ALC897 or similar) or the Intel Smart Sound Technology (SST) / Sound Open Firmware (SOF) digital microphone arrays used in modern MSI Raider laptops.

When the sound bar moves in your volume mixer but no audio comes out of the physical speakers, it means Linux thinks it is sending sound to the right place, but the hardware amplifier remains unpowered or unrouted.

Step 1: Force Intel DMIC/SST Detection

Modern laptops route the internal microphone and speakers through Intel's digital microphone (DMIC) subsystem, which frequently breaks on Linux. You can force the traditional Intel HDA fallback driver to see if it wakes the hardware up.

Open your terminal (Ctrl + Alt + T).
Open the GRUB configuration file:

sudo nano /etc/default/grub
Look for the line starting with GRUB_CMDLINE_LINUX_DEFAULT.
Append snd_hda_intel.dmic_detect=0 inside the quotes. It should look something like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"
Save and exit (Press Ctrl + O, Enter, then Ctrl + X).
Update your bootloader so the changes take effect:
- For Kubuntu: sudo update-grub
- For Fedora: sudo grub2-mkconfig -o /boot/grub2/grub.cfg
Reboot your laptop.

Step 2: Clear Corrupted PipeWire/WirePlumber Cache

Both Fedora 44 and modern Kubuntu releases utilize PipeWire and WirePlumber to manage audio routing. If the system state gets confused during installation or kernel upgrades, it can permanently mute the local node.

Purge the cached state file using this script block:

rm -rf $HOME/.local/state/wireplumber/* systemctl --user restart wireplumber pipewire pipewire-pulse

Test your audio immediately after running this to see if the mapping resets.

Step 3: Use ALSA-Tools to Force Pins (If Step 1 & 2 fail)

If you get audio through headphones but nothing through the main laptop speakers, the speaker pins are mismapped.

Install the ALSA tools GUI:
- Kubuntu: sudo apt install alsa-tools-gui
- Fedora: sudo dnf install alsa-tools
Launch the utility from your terminal: bash

sudo hdajackretask
Select your Realtek card from the drop-down menu at the top.
Check the box for "Show unconnected pins".
Look for overrides related to Internal Speaker. You may need to manually change an unassigned pin to Internal Speaker (Front) or Internal Speaker (Back) to force the laptop's physical amplifier to turn on.
Click "Apply now"

to test, and if it works, click "Install boot override" to make it permanent.

To narrow this down further, let me know:

When you run lspci -v | grep -A7 -i "audio", what audio controller models does your system list?
Do wired headphones plugged into the audio jack work, or is everything completely dead?

Knowing this will tell us if the issue is a missing firmware blob or an amplifier pin routing layout error.

Tried Step 1 and 2 on both Fedora and Kubuntu 26.04. I went through a days each with the google Gemini. I believe I used the ALSA tools but I'll try again and post what I'm seeing. I'll install 26.04 to stick with the newest kernel build. I believe my realtek card wouldn't populate on the ALSA tools but I'll confirm. Thanks more to follow.

I've updated the firmware and pulled new kernels namely 7.0.0. I modified UCM files multiple times.

Sounds like a few of you are using AI like I have been doing the past 3-4 days. I've used AI for Fedora, 26.04 on a clean install and here on 24.04 all which yielded no sound. I've resorted to using ChatGPT which led me down the UCM modification and modding the kernel and some other tables for the past 2 days. I think this hardware being so new I may just have to wait on a fix from the devs.

I'll do a test on an Arch based linux distro and see if the issue persists. I've also traded this laptop for the legion 9i with almost the same specs. The audio worked fine out of the box but I went back to the Raider due to the price.
