Public bug reported: It looks like 20.04 is now using sound open firmware (sof), however, sof does not have a driver(?) for Intel Comet Lake processors (which my Lenovo X1 Carbon Gen 7 laptop has). Here is the relevant output of dmesg: [ 3.272336] sof-audio-pci 0000:00:1f.3: warning: No matching ASoC machine driver found [ 3.272343] sof-audio-pci 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if 0x040380 [ 3.272485] sof-audio-pci 0000:00:1f.3: use msi interrupt mode [ 3.323370] sof-audio-pci 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 3.355159] sof-audio-pci 0000:00:1f.3: hda codecs found, mask 5 [ 3.355161] sof-audio-pci 0000:00:1f.3: using HDA machine driver skl_hda_dsp_generic now [ 3.377802] sof-audio-pci 0000:00:1f.3: Direct firmware load for intel/sof/sof-cnl.ri failed with error -2 [ 3.377805] sof-audio-pci 0000:00:1f.3: error: request firmware intel/sof/sof-cnl.ri failed err: -2 [ 3.377808] sof-audio-pci 0000:00:1f.3: error: failed to load DSP firmware -2 [ 3.377809] sof-audio-pci 0000:00:1f.3: error: sof_probe_work failed err: -2
