I was using Tumblweed on my P1 Gen 8 Lenovo laptop but due to the Nvidia GPU updates and CUDA , I changed it to Leap 16. all works fine but internal sound.
HDMI and bluetooth speaker works fine just internal sound " Dummy".
is there way to fix it ?
Since this worked on Tumbleweed, it’s likely a kernel/firmware issue on Leap 16. Report back with results from
inxi -Aaz
aplay -l
pactl list cards
sudo dmesg | grep -i firmware
Yes, I think it kernel issue. here is the result back from the commands:

Leap is loading the **legacy snd_hda_intel driver instead of the snd_sof_pci_intel_mtl driver. To load the SOF driver, make sure the firmware is installed first…
sudo zypper install sof-firmware
Also, add the snd_intel_dspcfg.dsp_driver=1 boot parameter to tell the kernel to use the SOF DSP driver…
sudo update-bootloader --add-option snd_intel_dspcfg.dsp_driver=1
sudo update-bootloader --config
and reboot.
Actually, just try installing the sof-firmware package and leave out the kernel parameter. From what I’ve since read that will disable the SOF driver (which is not the outcome we want).
yes, that is not goingto help.
So, did you manage to get the SOF driver loaded instead?
I loaded but nothing changed
A bit vague…are you saying you installed the firmware package (no grub boot parameter used), rebooted and confirmed that the SOF driver was in use?
inxi -Aaz
You may have to go back to sound settings and select something other than dummy
No, the dummy output isn’t a selection problem, it is a symptom of an underlying issue.
PipeWire only creates “Dummy Output” when no valid ALSA sinks are available. The OP’s aplay -l output already showed only HDMI devices present, with no internal speaker device enumerated at all.

Thanks for your explanation.
Last fall I bought two Lenovo refurbished laptops and one got Fedora as I knew they’re well supported and the other Tumbleweed.
Fedora got the sof-firmware package automatically on installation and Tumbleweed didn’t, so after looking around for a minute in KDE and seeing no devices in Sound I checked dmesg and that had the firmware missing information I needed to look for the package and install it - but I don’t remember if I did something else after reboot or didn’t have to.
No further action is generally required.

I used both Ubuntu and Tumblweed on this laptop. both was working. but Leap just shows the Dummy output
That shows the same snd_hda_intel driver loaded (rather than snd_sof_pci_intel_mtl).
-
You should compare the output produced with Ubuntu, and report back.
It may be that a newer kernel is required to properly support this hardware. -
Try explicitly loading it…
sudo update-bootloader --add-option snd_intel_dspcfg.dsp_driver=3
sudo update-bootloader --config
reboot
Confirm that inxi shows snd_sof_pci_intel_mtl loaded, and check sound again.

I probably will not install ubuntu on this laptop.
Is this output from Ubuntu? Did you try step 2 as well?
No this is Leap output. I odn’t have Ubuntu anymore.
I have did both steps
Please show the output of
dmesg | egrep -i "sof|firmware"
Let’s see if there are any firmware errors.
