我在我的笔记本电脑上运行 Debian 10。
我尝试安装realtek alc665声卡的驱动程序。我失败了，结果我的系统上没有声音。我可以播放歌曲，但我听不到任何声音，尽管音量控制可用且很高。
当我运行pavucontrol音频混合器时，在配置选项卡中我看到：
no cards available for configuration
在输出设备选项卡中我看到dummy output
我打开了一个终端，这是以下输出lspci -v：（此列表中仅音频设备）

输出形式lshw -c multimedia也可能有用：

当我跑步时alsa –version ，我得到了这个：
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

最后这是输出aplay -l：

目前似乎有可用的驱动程序，但不适用于pulseaudio。那么我该如何解决这个问题呢？
答案1
我收到此错误是因为我最近安装了 TiMidity++（以使用 Linthesia 获取声音）并且它在启动时自动启动。
也许它不能解决你的问题，但为了再次通过 PulseAudio 获得声音，我必须停止 TiMidity++ 服务，例如，如果你的 Linux 发行版使用 Systemd，你可以使用命令systemctl stop timidity来停止服务并systemctl disable timidity禁用服务自动启动。
