I am not sure if this is related to the MIC not working: [ 160.122834] snd_hda_codec_realtek ehdaudio0D0: didn't find PCM for DAI Digital Codec DAI [ 160.122837] snd_hda_codec_realtek ehdaudio0D0: ASoC: error at snd_soc_dai_startup on Digital Codec DAI: -22 [ 160.122839] Digital Playback and Capture: ASoC: BE open failed -22 [ 160.122841] HDA Digital: ASoC: failed to start some BEs -22 [ 160.122881] snd_hda_codec_realtek ehdaudio0D0: didn't find PCM for DAI Digital Codec DAI [ 160.122882] snd_hda_codec_realtek ehdaudio0D0: ASoC: error at snd_soc_dai_startup on Digital Codec DAI: -22 [ 160.122883] Digital Playback and Capture: ASoC: BE open failed -22 [ 160.122884] HDA Digital: ASoC: failed to start some BEs -22 I posted the full output on http://alsa-project.org/db/?f=45fc657ecf37976734035202625a3c08841d7361 Firmware wise I downloaded the sof firmware from https://github.com/thesofproject/sof-bin/, I am not sure if the "unknown sof_ext_man header" message could be the problem: [ 48.431640] sof-audio-pci-intel-tgl 0000:00:1f.3: Firmware info: version 1:7:0-47d07 [ 48.431642] sof-audio-pci-intel-tgl 0000:00:1f.3: Firmware: ABI 3:18:1 Kernel ABI 3:18:0 [ 48.431643] sof-audio-pci-intel-tgl 0000:00:1f.3: unknown sof_ext_man header type 3 size 0x30 [ 48.530671] sof-audio-pci-intel-tgl 0000:00:1f.3: Firmware info: version 1:7:0-47d07 [ 48.530675] sof-audio-pci-intel-tgl 0000:00:1f.3: Firmware: ABI 3:18:1 Kernel ABI 3:18:0 [ 48.534529] sof-audio-pci-intel-tgl 0000:00:1f.3: Topology: ABI 3:18:1 Kernel ABI 3:18:0 I also verified: the microphone of an external headset still works - so basically the behaviour is the same as without the sof module.
