I would make sure the BIOS and especially the Intel ME firmware is up to date (check fwupd). https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t14-type-20s0-20s1/downloads/ds544549-bios-update-utility-bootable-cd-for-windows-10-64-bit-linux-thinkpad-p14s-gen-1-p15s-gen-1-t14-gen-1-t15-gen-1?category=BIOS%2FUEFI
The Intel ME is responsible for authenticating the SOF firmware and I've seen older versions cause strange errors like this. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/2121736 Title: Audio not working on Lenovo ThinkPad T14 with Ubuntu 24.04 – SOF driver (sof-audio-pci-intel-cnl) fails to boot DSP firmware (err: -110), results in Dummy Output. Status in alsa-driver package in Ubuntu: New Bug description: Description: On Lenovo ThinkPad T14 running Ubuntu 24.04, the default SOF (Sound Open Firmware) driver fails to initialize. As a result, PipeWire / PulseAudio only shows Dummy Output, and no audio devices are available. System details: Model: Lenovo ThinkPad T14 CPU/Chipset: Intel Comet Lake PCH-LP cAVS [8086:02c8] Ubuntu version: 24.04 LTS (Noble Numbat) Kernel driver in use: sof-audio-pci-intel-cnl Kernel modules loaded: snd_hda_intel, snd_sof_pci_intel_cnl, snd_soc_avs, ... Audio stack: PipeWire (with PulseAudio compatibility) Observed behavior: After system update, audio output disappeared. pactl list short sinks shows only auto_null. dmesg logs show repeated SOF DSP boot failures: sof-audio-pci-intel-cnl 0000:00:1f.3: cl_dsp_init: timeout with rom_status_reg (0x80000) read sof-audio-pci-intel-cnl 0000:00:1f.3: error: dsp init failed after 3 attempts with err: -110 sof-audio-pci-intel-cnl 0000:00:1f.3: Failed to start DSP sof-audio-pci-intel-cnl 0000:00:1f.3: error: failed to boot DSP firmware -110 Expected behavior: SOF driver should successfully load firmware and expose audio devices without requiring manual intervention. Workaround: Disabling SOF and forcing the kernel to use the legacy HDA driver restores audio: echo "options snd-intel-dspcfg dsp_driver=1" | sudo tee /etc/modprobe.d/disable-sof.conf sudo update-initramfs -u reboot With this setting, audio devices appear normally, and sound works again. Steps to reproduce: Install Ubuntu 24.04 LTS on Lenovo ThinkPad T14 (Comet Lake). Boot the system (with default SOF driver). Check pactl list short sinks → only auto_null. Inspect logs (dmesg | grep -i sof) → DSP boot errors. Notes: Package firmware-sof-signed was installed (version 2023.12.1-1ubuntu1.6, upgradable to .7). Issue persists even after reinstalling alsa-base, pipewire, wireplumber, and linux-firmware. Switching to snd-hda-intel resolves the issue completely.
