問題：內建麥克風不工作
問題：如何讓麥克風正常運作？
設定:
- 型號：戴爾 Precision 7530
- 作業系統：Ubuntu 22.04
- 核心版本：5.17.0-1025-oem（最近從非oem切換而來）
我已經嘗試過：
- 在 Pavucontrol 中選擇立體聲雙工
- 在 Pavucontrol 中取消靜音
- 檢查 Alsamixer 中的麥克風電平（儘管只有“耳機”和“耳機”選項，而沒有整合麥克風的選項）
- 重新安裝 alsamixer 和pulseaudio
- 將 /etc/modprobe.d/alsa-base.conf 中的“snd_hda_intel”列入黑名單
- 安裝 SOF 韌體和拓撲二進位文件
- 在具有 3.5 毫米插孔的耳機和 USB 網路攝影機上測試外部麥克風（兩者均開箱即用）
- 檢查其他答案

答案1
經過進一步挖掘，我明白了。
我的筆記型電腦根本沒有內建麥克風。
這可能會讓人感到驚訝，但顯然並不是每台筆記型電腦都有內建麥克風。
