[Dell 2-in-1] My speakers aren’t detected and no sound can be output

Support and Help

Ubuntu Version:

25.04

Desktop Environment (if applicable):

GNOME

Problem Description:

When using Ubuntu, my speakers aren’t detected and no sound can be output. See also No Audio on Lunar Lake Laptop with 25.04

Relevant System Information:

I’m using a Dell DB06250.

What I’ve Tried:

Checking for updates and installing the latest kernel in plucky-proposed.

The main reason I’m opening this is because No Audio on Lunar Lake Laptop with 25.04 has been locked and I have a question. The person replying to the thread claimed that 6.15 would be brought to Plucky “soon” - however, I took a look at the kernel package(s) and haven’t seen any proof of this happening before? Is this actually planned, is a patch of some kind coming for Plucky or will I have to wait for Questing/use an unsupported mainline kernel?

Ubuntu follows a stable release model for it’s OS, so the 6.14 kernel will remain the kernel of Ubuntu 25.04 for the life of the release.

Ubuntu questing is currently using the 6.15 kernel

guiverc@d7050-next:~$   rmadison linux-generic |grep questing
linux-generic | 6.14.0-13.13.1         | questing          | riscv64
linux-generic | 6.15.0-4.4             | questing          | amd64, arm64, armhf, ppc64el, s390x
linux-generic | 6.16.0-13.13           | questing-proposed | amd64, arm64, armhf, ppc64el, s390x

but questing when it reaches release as Ubuntu 25.10 will have moved beyond 6.15; so the only place where I’d expect a chance of seeing 6.15 as a supported kernel maybe as an OEM option for some specific hardware.

The 6.15 you read may have been a typo OR I do see it mentioned in relation to an OEM kernel, where OEM kernels are built for specific hardware and thus don’t follow the generic kernels in version.

right - from what I’ve seen, Questing will target 6.17 assuming it’s out in time.

the thing with OEM kernels is I was (somewhat) under the impression that they’re only used for LTS releases? if they’re also sometimes done for non-LTS releases then fair enough but yeah

obviously I could just wait for the stable release of 25.10 but not having audio for 2-3 months isn’t exactly ideal so hmmm

I can’t help with OEM kernels sorry.

As the OEMs (companies seeking help from Canonical with newer products) change regularly over time, what is available for prior releases isn’t always a good clue as to what will happen in the future, and I don’t try and keep up with OEM kernels.
