The internal microphone on the Lenovo ThinkPad E16 model requires a quirk entry to work properly. This was fixed in a previous patch (linked below), but depending on the specific variant of the model, the product name may be "21M5" or "21M6".

The following patch fixed this issue for the 21M5 variant: https://lore.kernel.org/all/20240725065442.9293-1-tiwai@suse.de/

This patch adds support for the microphone on the 21M6 variant.

Link: https://github.com/ramaureirac/thinkpad-e14-linux/issues/31 Cc: stable@vger.kernel.org Signed-off-by: Thomas Mizrahi thomasmizra@gmail.com --- I recently acquired a ThinkPad E16 Gen 2 AMD and could not get the internal microphone working. After some research, I discovered this issue. Since my machine is a 21M6 variant, the required quirk was not applied by the existing patch. After applying this patch and testing on my machine, the microphone was immediately recognized and worked without further issues.
