Created attachment 307282 [details] Patch that possibly fixes the issue Basically the same as https://bugzilla.kernel.org/show_bug.cgi?id=216925 External microphones work, internal doesn't. I've made a patch similar to that another issue (attached), but had issues running with the recompiled kernel, so not yet sure it works. $ lspci|grep Audio c4:00.1 Audio device: Advanced Micro Devices, Inc.

Just tested the patch, and it works fine, I get sound from the mic. Both the short "21ME" and the long "21MES00B00" work for the product name, although I don't understand why.
The problem is, I don't see "acp6x" in the dmesg output. Should I? $ sudo dmesg | grep 'acp6x\|DMIC\|snd\|udio' [ 6.000040] snd_hda_intel 0000:c4:00.1: enabling device (0000 -> 0002) [ 6.000324] snd_hda_intel 0000:c4:00.1: Handle vga_switcheroo audio client [ 6.003989] snd_hda_intel 0000:c4:00.6: enabling device (0000 -> 0002) [ 6.016977] snd_hda_intel 0000:c4:00.1: bound 0000:c4:00.0 (ops amdgpu_dm_audio_component_bind_ops [amdgpu]) [ 6.041615] input: HD-Audio Generic HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:08.1/0000:c4:00.1/sound/card0/input15 [ 6.041725] input: HD-Audio Generic HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:08.1/0000:c4:00.1/sound/card0/input16 [ 6.041828] input: HD-Audio Generic HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:08.1/0000:c4:00.1/sound/card0/input17 [ 6.068296] snd_hda_codec_realtek hdaudioC1D0: autoconfig for ALC257: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:speaker [ 6.068301] snd_hda_codec_realtek hdaudioC1D0: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) [ 6.068303] snd_hda_codec_realtek hdaudioC1D0: hp_outs=1 (0x21/0x0/0x0/0x0/0x0) [ 6.068304] snd_hda_codec_realtek hdaudioC1D0: mono: mono_out=0x0 [ 6.068306] snd_hda_codec_realtek hdaudioC1D0: inputs: [ 6.068307] snd_hda_codec_realtek hdaudioC1D0: Mic=0x19 [ 6.068317] snd_pci_ps 0000:c4:00.5: enabling device (0000 -> 0002) [ 6.108190] input: HD-Audio Generic Mic as /devices/pci0000:00/0000:00:08.1/0000:c4:00.6/sound/card1/input18 [ 6.108296] input: HD-Audio Generic Headphone as /devices/pci0000:00/0000:00:08.1/0000:c4:00.6/sound/card1/input19
