1. 除非你額外安裝音效卡或音效裝置否則不需要額外安裝聲卡驅動
Ubuntu 預裝 alsa 提供聲卡驅動預裝 pulseaudio 服務音效事宜

0. 也有可能是設定的問題

1. 詳細描述一下你使用的喇吧.
1-1. 如果是電腦預裝的喇吧
1-1-1. Bios 音效設定有沒有 AC'97 (Audio Codec '97) 或 HDA (Intel High Definition Audio) 選項嗎
1-1-2. 以上如果不確定請提供電腦品牌及詳細型號.

2. 安裝 pavucontrol 套件
2-1. 從終端機執行 pavucontrol
把 Playback / Output Devices / Configuration 三個標籤畫面擷圖貼上來

3. 從終端機執行
3-1. aplay -L # L 大寫
3-2. aplay -l # L 小寫
把結果複製貼上來

4. 如果是電腦預裝的聲卡
把下面指令複製貼進終端機執行
4-1. sudo lshw -numeric -class multimedia
把結果直接複製貼上來
