The solution for me was:
1) install mainline ``` udo add-apt-repository ppa:cappelikan/ppa sudo apt update && sudo apt upgrade -y sudo apt install -y mainline ``` kernel for sound 6.9.12 2) isntall sound driver over systems (remove the system ones) ``` sudo rm -r /lib/firmware/intel/sof-ipc4-tplg sudo rm -r /lib/firmware/intel/sof-ace-tplg sudo rm -r /lib/firmware/intel/sof-ipc4 git clone https://github.com/thesofproject/sof-bin sudo ./install.sh v2.9.x/v2.9 (make sure it prints links are created) cp -r tools-v2.9/ /usr/local/bin/ ``` 3) install sound codecs sudo apt-get install ubuntu-restricted-extras # use pavucontrol to enable sound driver in config tab pactl list short sinks # set second from the list as default pactl set-default-sink alsa_output.pci-0000_00_1f.3-platform-sof_sdw.pro-output-2 4) debug issues with chat gpt, but don't reinstall packages if it suggest so ``` journalctl --user -xe | grep pipewire sudo dmesg | grep snd sudo dmesg | grep pipewire sudo dmesg | grep sof sudo dmesg | grep audio ``` 5) maybe not needed but I edit ``` gedit /usr/share/pipewire/pipewire.conf default.clock.rate = 44100 default.clock.allowed-rates = [ 44100, 48000 ] ``` -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to firmware-sof in Ubuntu. https://bugs.launchpad.net/bugs/2058691 Title: No sound card detected on the Dell xps 16 2024 (9640) Status in firmware-sof package in Ubuntu: Fix Committed Bug description: The sound card is not detected on the Dell XPS 16 2024 (9640).
