Dell XPS 14 9440 Support

[Yellow Pasque]

complaining about a missing topology file 'sof-mtl-rt711.tplg'

Shot in the dark here, but maybe the file it should be looking for is sof-mtl-rt711-4ch.tplg (this laptop has quad speakers from what I can see). Try making a symbolic link (and rebooting):

cd /lib/firmware/intel/sof-ace-tplg/
sudo ln -s sof-mtl-rt711-4ch.tplg sof-mtl-rt711.tplg

If it doesn't work, look at dmesg again to see if anything changed.

Whether it works or not, maybe open an issue here: https://github.com/thesofproject/sof-bin/issues I'm going to guess they will make a link in their repo like I did or get/create the missing file if needed. Either that, or they can figure out where the reference to "sof-mtl-rt711.tplg" is coming from and fix that.

however i didn't got icamera to compile https://github.com/intel/icamerasrc/...rasrc_slim_api

for details check: https://askubuntu.com/questions/1508...-lake-platform

To me, it looks like you either need gstreamer 1.24.x or maybe an older version of icamera.

So...i found this thread https://github.com/thesofproject/linux/issues/4879 and it's for the 16" 9640, but i assume it's a similar audio device in the 9440.

I'm not an expert in any of this, but it sounds like the latest kernel seems to be picking up the audio device incorrectly, and thinking it needs to use the rt711 drivers, but it should actually be the cs35l56 driver. And the fix is available (or it works in one of the latest beta Linux kernels.

So using mainline, i changed my kernel to 6.9-rc2 (Beta/Release Candidate) rebooted and it's now seemingly using the right driver, but i'm still can't get the audio device to appear, and still only see "Dummy Output" as a device.

For reference, here's a dump of dmesg

But the moritz89 seems to have got it working, but i don't know how.
Anyways, figured i'd post, see if it helps

[Yellow Pasque]

it's now seemingly using the right driver, but i'm still can't get the audio device to appear, and still only see "Dummy Output" as a device.

In addition to the latest sof firmware, did you update the ucm like in https://github.com/thesofproject/lin...ent-2027703266
Make sure you do that and reboot.

What does this show?:

OK, follow the same steps in the link, but no joy. Seems to be same issue.

OK update - Working Audio on Dell XPS 14" (9440)!

So, Ubuntu 24.04 got released in Beta a few days ago (https://releases.ubuntu.com/noble/)
So...downloaded ubuntu-24.04-beta-desktop-amd64.iso to USB and installed it. This time i actually selected to install third party drivers, and it seems happy (Working GFX card) and is showing a 4050 GTX in System Details

This version of Ubuntu comes with 6.8.0-22-generic kernel

So i installed mainline
sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt install mainline
And updated the kernel to 6.9-rc3 (latest but i suspect some earliers would work too)

Then downloaded latest available sof binaries from https://github.com/thesofproject/sof-bin/releases (v2024.03)
Extracted tar and then ran install.sh as sudo (Had issues with some folder not extracting/removing properly so removed contents of /lib/firmware/intel/sof-ace-tplg first and re-ran installer again)


Then as per @Yellow Pasque comment, i "patched UCM" as per the thread in github issue (https://github.com/thesofproject/lin...ent-2024076848)

curl -L -o alsa-ucm-conf.tar.gz https://github.com/alsa-project/alsa.../master.tar.gz
tar xvzf alsa-ucm-conf.tar.gz -C /usr/share/alsa --strip-components=1 --wildcards "*/ucm" "*/ucm2"
Rebooted and....Working audio!


If anyone needs any further info, let me know

It is nice that you got your Ubuntu 24.04 work on XPS 14 9440! I just wonder if all the hardware worked well with the latest released Ubuntu apart from audio and graphic card. For instance, camera, touchpad (did you test if the haptic touchpad also works). Thanks!
It seems that updated kernel is major factor influencing the compatibility, right? Perhaps, this is why Pop os, which supports kernel 6.8, could work as well for someone.

[mixer2]

@dook123 nice that you got audio working, thanks for the effort!
what's a pitty is, that it requires a mainline kernel verison. hopefully it will at some point also just work with the ubuntu 24.04 kernel.

regarding webcam it seems as also the 16" 2024 dell notebooks have the same issue: https://github.com/intel/ipu6-drivers/issues/223

hopefully they'll fix it soon in the ipu6 drivers.

Hello,

how is, beside general hardware support your overall experience?
for me, after working for quite some time with the xps 14, it's still not completely reliable, as my old xps 13 was. it's working perfectly fine most of the time (beside webcam, of course), it's super fast and has good battery life.
however, wakeing up from standby is ~90% of the time working, but sometimes it isn't and i have to reboot. sometimes i have graphical glitches... and sometimes the system just hangs for 30-60 seconds, which is especially bad in video conferences while sharing the screen.
last problem is, that when it's connected/disconnected to/from an external display. sometimes it also crashes.
i use wayland with latest nvidia drivers (however, set it to intel mode, because i hoped that it might help with graphical glitches, which it didn't).

another problem, which is not linux related is, that usb-c connection to usb-c dell monitors causes the pc to shut down after a few seconds. this also happens on windows (and is not a hardware problem, tried it with 2 devices). other usb-c monitors work fine. it has to be some special communication between the dell products.

just wondering what the experiences of other users are

Hello,

how is, beside general hardware support your overall experience?
for me, after working for quite some time with the xps 14, it's still not completely reliable, as my old xps 13 was. it's working perfectly fine most of the time (beside webcam, of course), it's super fast and has good battery life.
however, wakeing up from standby is ~90% of the time working, but sometimes it isn't and i have to reboot. sometimes i have graphical glitches... and sometimes the system just hangs for 30-60 seconds, which is especially bad in video conferences while sharing the screen.
last problem is, that when it's connected/disconnected to/from an external display. sometimes it also crashes.
i use wayland with latest nvidia drivers (however, set it to intel mode, because i hoped that it might help with graphical glitches, which it didn't).

another problem, which is not linux related is, that usb-c connection to usb-c dell monitors causes the pc to shut down after a few seconds. this also happens on windows (and is not a hardware problem, tried it with 2 devices). other usb-c monitors work fine. it has to be some special communication between the dell products.

just wondering what the experiences of other users are

Yeah definitely not perfect, lots of issues with wake up, and unlocking after wakeup.
I haven't had any issues with my Dell monitors and USB-C, but i have noticed that any dongle that has the 2 x USB-C ports won't fit this. Soooo infuriating.
I loved my 2020 13" XPS, but this one just is not as good at all. Kind regret buying it tbh, and might sell to in place of something else
