Internal microphone does not work with 5.12 (Tiger Lake, X1 Nano)

[Nico Schottelius]

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

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

[   48.530671] 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.
