数字立体声 (HDMI) 输出（未插电）- NVidia GTX 970

我在通过 HDMI 传输音频时遇到了问题。我的显示器通过 HDMI 电缆连接，但音频无法正常工作。在默认的 ubuntu 声音设置中看不到 HDMI 音频输出。在pavucontrol配置选项卡中安装后，分配给 nvidia 声音驱动程序的所有输出都显示为未插电。是否有任何选项可以“插入”这些音频输出。

到目前为止我尝试过：

  • 升级 NVidia 驱动程序（当前运行 361.28）
  • 安装每日 alsa 驱动程序（oem-audio-hda-daily-dkms来自 ppa:ubuntu-audio-dev/alsa-daily repo）
  • 卸载/重新安装 pulseaudio
  • 发行版升级
  • 玩 xorg.conf 文件
  • 启用 alsamixer 中的所有功能
  • 使用不同的 HDMI 电缆（不幸的是，我无法使用其他接收器）
  • hw:1,3启用设备的静态负载/etc/pulse/default.pa
  • 具有切换模式的多个xrandr命令，打开/关闭设置为自动并将音频设置为开启

我从 Windows 转移过来并且 HDMI 声音工作正常。

下面的一些链接也许可以提供更多信息。
