软件信息

该问题如标题所示，很具体，所以让我演示一下我的问题。

我可以在电脑上听到 Opera 的声音。有时，我会将其插入智能电视，然后从那里听到声音和屏幕（手动，通过打开声音设置并将 HDMI 设置为默认声音输出）。

昨天，我拔掉电源并尝试打开 Youtube 视频，但我听不到任何声音。我测试了声音，可以听到来自计算机的测试声音。我在 Firefox 中测试，声音运行良好，这意味着这不是驱动程序的问题（或者我认为如此）。

附加信息

我有双启动。当我使用 Windows (10) 时，我会手动从扬声器切换到耳机或反之亦然。我的系统信息将位于最底部。

答案1

我遇到了同样的问题，我通过以下方法解决了它：在“声音设置”中，我转到右侧的应用程序选项卡。在那里我更改了几项（不记得具体是哪些了），比如音量，选中并取消选中静音选项，然后声音就恢复了。我的 Opera 版本是 42.0.2393.137。希望这个方法也适用于你！
