我正在运行 ubuntu 16.04 并连接到带有 HDMI 的 Onkyo 接收器以获取声音。最初一切正常，我可以选择 HDMI 输出设置 > 声音 > 输出。发生了一些事情，现在我不再在其中看到 HDMI 选项设置 > 声音 > 输出当查看脉冲音频音量控制时，所有 HDMI 选项都列为已拔出。
我能够在电视上进行测试，一切正常，所以不是电缆的问题。它也不是接收器，因为如果我使用 tty1 终端ctr + alt + f1选择 HDMI 声音后，声音突然按预期出现。当我切换回 GUI 时ctr + alt + f7声音再次静音。
我尝试过的事情
脉冲音频-k
检查 alsamixer 的静音通道（一切都显示 00）
搞乱了“pacmd set-card-profile 0 输出：hdmi-stereo”命令组合
手动删除.config/pulseaudio 文件
通过禁用脉冲音频
mkdir ~/.pulse
echo autospawn=no > ~/.pulse/client.conf
脉冲音频-k
pacmd -list-cards 输出
