With the 5.4 kernel, the sound driver could detect audio dsp and dmic runtime, on this mahcine, the driver found them, then it abort the legacy hda driver: [ 13.711820] snd_hda_intel 0000:00:1f.3: Digital mics found on Skylake+ platform, aborting probe
Then the sound driver load the sof driver, but it finally failed to find the tplg file for this machine: [ 14.056300] sof-audio-pci 0000:00:1f.3: Direct firmware load for intel/sof-tplg/sof-hda-generic-4ch.tplg failed with error -2 [ 14.056303] sof-audio-pci 0000:00:1f.3: error: tplg request firmware intel/sof-tplg/sof-hda-generic-4ch.tplg failed err: -2 For sof firmware and tplg, Intel has not released sof-hda-generic- 4ch.tplg to us, then we didn't integrate it to ubuntu yet. So for using the legacy hda driver forcibly, please add the module parameter dmic_detect=0 to the snd-hda-intel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1860697 Title: Sound doesn't work on Lenovo X1 Carbon with 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1860697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
