答え1
サウンドカードの識別を使用して起動しlspci -nn、ロードされたサウンドモジュールの識別を使用し、lsmodでコーデックチップの名前を見つけ、通常は/proc/asound/card*/codec\#*起動dmesg後に出力を読み取って保持しているハードウェアを確認できます。
これまで見たことがありません。どのI2Sを使用してノートパソコンまたはデスクトップにコーデックを接続します。これは、組み込みシステムがある場合はそのシステムで行われます。したがって、HDAカードを所持することは非常に安全です。

あなたのサウンドカードは
00:03.0 Audio device [0403]: Intel Corporation Broadwell-U Audio Controller [8086:160c] (rev 09)

接続したWikiページによれば、最初のサウンドカードは、broadwell-rt286I2Sモード（ACPI起動時に決定されます）でALSAデバイスとして表示される必要があります。だから確認してくださいcat /proc/asound/cards。しかし、私の考えでは、PCIの説明にもかかわらず、「Broadwell-U」は「Broadwell RT286」と同じではないようです。
クイックGoogle検索を公開これI2Sの使用例：HDA HDMIサウンドカードの残りの部分を駆動するモジュールsnd_soc_*に加えて、いくつかのアクティブモジュール（soc =システムオンチップ、通常は組み込みデバイスでのみ使用されると言われています）があります。snd_hda_*に対応broadwell-audioとhaswell-pcm-audioメッセージがありますdmesg。あなたがそれを持っていないので、私の推測はまだ「HDA」ですが、決定するのに十分な情報を提供していません。
この内容がまだ混乱している場合は、次のように入力してください。いっぱい出力を開始したら、dmesg出力をPastebinまたは同様のファイルcat /proc/asound/cardsに貼り付け、リンクで質問を編集します。lsmodcat /proc/asound/card*/codec\#*
