オーディオエラー：intel / sof / sof-cml.riへの直接フ​​ァームウェアロードがエラー-2のために失敗しました。

この質問はX1 Carbon第7世代についてです。第10世代インテル( Intel(R) Core(TM) i7-10710U)。第8世代Intelを搭載した一部のx1c7には他の問題が報告されていますlshw。

00:1f.3 Audio device: Intel Corporation Device 02c8 (prog-if 80)

オーディオが正しく機能しません。音やデバイスの検出は受信されません。カーネルで5.6.0-1-amd64多くのエラーが発生します。sof-audio-pci

これを示す唯一の出力ソースは仮想です。起動時にこのログを生成するX1 Carbon 7th Editionで動作するサウンドを取得できますか？
