我在我的筆記型電腦上運行 Debian 10。
我嘗試安裝realtek alc665聲卡的驅動程式。我失敗了，結果我的系統上沒有聲音。
當我運行pavucontrol音頻混合器時，在配置選項卡中我看到：
no cards available for configuration
在輸出設備選項卡中我看到dummy output
我打開了一個終端，這是以下輸出lspci -v：（此列表中僅音訊設備）

輸出形式lshw -c multimedia也可能有用：

當我跑步時alsa –version ，我得到了這個：
ALSA lib confmisc.c:767:(parse_card) cannot find card '0'
ALSA lib conf.c:4568:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

最後這是輸出aplay -l：

目前似乎有可用的驅動程序，但不適用於pulseaudio。那我該如何解決這個問題呢？
答案1
我收到此錯誤是因為我最近安裝了 TiMidity++（以使用 Linthesia 獲取聲音）並且它在啟動時自動啟動。
也許它不能解決你的問題，但為了再次透過 PulseAudio 獲得聲音，我必須停止 TiMidity++ 服務，例如，如果你的 Linux 發行版使用 Systemd，你可以使用命令systemctl stop timidity來停止服務並systemctl disable timidity停用服務自動啟動。
