我无法修复音频，因为我在 hp probook 650 G1 上安装了 debian。我什至不知道要寻找什么或尝试做什么。我陷入了这个来自pulseaudio的日志中。

好的一点是，alsa 可以识别您的卡，并且向 Soundsystem 的移交工作正在正常进行。
在 alsamixer 中控制是否静音。使用 F6，您可以选择您的卡 对于 alsamixer，您的系统上需要 apt-utils。没有运气？
sudo apt install pavucontrol
开始它pavucontrol
选项卡输出设备您将看到两种可能性。对于内部卡，选择端口扬声器。选项卡配置，您可以在其中选择卡的配置文件。我现在使用带有配置文件模拟立体声双工的内部卡。您 aplay /usr/share/sounds/alsa/Front_Center.wav可以控制配置文件是否有效。
