私はDebian 10を使用しています。設定、サウンド、入力に入ると、マイクがないかのようにすべてがグレー表示されます。
ただし、マイクが検出されますpavucontrol。
それでもマイクは機能しません（昨日まで、両方のパフォーマンスは状況がまったく同じでした）。実際には、2番目の図（「上級」の真上）の大きな青いバーに見られるように、騒音がたくさん発生します。設定で「検出されない」状況を解決することが、今日の「機能しない」問題を解決する最初のステップになる可能性があると思います。
どんなアイデアがありますか？

私はラップトップではなくデスクトップを使用しています。
USBマイクではなく、通常のP10コネクタ（ヘッドフォンコネクタとは別）を使用してください。
arecord -lマイクが接続されているかどうかにかかわらず、同じ結果が得られます。

「機械の中の幽霊」が私をからかっていました。
alsamixerAudacityの録音音量に影響を与える唯一のセクションは、以下の最も高いレベルのセクション「キャプチャー」です。
ベストアンサー1
部分的な答え：
どちらも
amixer -c0マイクが接続されているかどうかにかかわらず、まったく同じ結果を提供します。cat /proc/asound/card*/codec#*
これは、コーデックが何らかの理由でマイクが接続されているかどうかを検出できないことを意味します。
特に、BIOSがピンコンプレックスに誤った値を割り当てる場合（特にノートブックでは非常に一般的な間違い）を排除し、ALSAは単にコーデックの変更を許可しません（これも起こります）。
そのため、ハードウェアが故障したり（動作させる方法はありません）、正しい構成を設定してマイクを手動で取得できます。したがって、「未発見のケース」を解決することは役に立ちません。
音量設定を変更すると、ロードノイズにどのような影響がありますか？どの設定が影響し、どの設定が影響しませんか？

さて、私が到着したコーデックマッピングトポロジで
N = Node P = Pin M = Mixer I = Audio In O = Audio Out S = Selector
V = Vendor
O02 "Front"
O03 "Speaker"
O04 "Surround"
O05 "Center"
O06 "Digital"
V07
I08 <- N23 Main
I09 <- N22 Alt
I0a <- P1f Digital
M0b <- P18 P19 P1a P1b P1c P1d P14 P15 P16 P17
M0c <- O02 M0b "Loopback 1"
M0d <- O03 M0b "Loopback 2"
M0e <- O04 M0b "Loopback 3"
M0f <- O05 M0b "Loopback 4"
O10 "Digital"
P11 Line out
P12 ?? Speaker Ext Rear
V13
P14 <- M0c OUT Line Out Ext Rear
P15 <- M0d OUT Speaker Int
P16 <- M0e IN Speaker Ext Rear Black
P17 <- M0f IN Speaker Ext Rear Black
P18 <- M0c M0d M0e M0f N26 IN Mic Ext Rear
P19 <- M0c M0d M0e M0f N26 IN Mic Ext Front
P1a <- M0c M0d M0e M0f N26 IN Line In Ext Rear
P1b <- M0c M0d M0e M0f N26 OUT HP Out
P1c IN
P1d IN
P1e <- O06 OUT DIG
P1f IN
V20
V21
M22 <- P18 P19 P1a P1b P1c P1d P14 P15 P16 P17 M9b P12 Alt
M23 <- P18 P19 P1a P1b P1c P1d P14 P15 P16 P17 M9b Main
V24
O25
M26 <- O25 M0b
これは、P16とP17がBIOSによってエラーとしてマークされ（OUTでなければならない）、接続されていない可能性があることを意味します。 M22とM23は2入力録音ミキサー、M0bはループバックミキサーです。
ALSAラベルを見ると、ALSAはトポロジに混乱を感じ、ラベルを誤って割り当てたようです。
したがって、あなたが聞くのは、録音中にALSAが間違った接続をしたため、コーデックのどこかで捕捉されたノイズだけです。
1）MICを接続していない状態でコーデックダンプを実行し、それを接続してから2番目のコーデックダンプを実行して検索を再テストします。両方のダンプをdiff。あなたしなければならないノードP18またはP19の違いを確認してください。その違いは非常に小さいです。
2) hdajackretaskP16 と P17 を修正して、ALSA を混同しないことを確認できます。
3）コーデックの仕組みを理解したら、パッケージhda-verbの内容を使用して、alsa-tools録音中にALSAによって割り当てられた誤った割り当てを手動で修正し、それが正しいことを確認できます。
4）ALSA開発者（google）にバグレポートを送信し、誤った割り当てを表示するのに十分なコーデックダンプを含めます。
