我在 Raspberry Pi 4 上运行 VLC Player，通过 HDMI 连接到电视，电视是连接到 Pi 的唯一输出设备。我目前不关心音乐，我只想修复视频的默认音频输出，尽管我只会将此 Pi 与电视一起使用，因此我理想情况下希望所有音频都通过 HDMI 路由。
当我从 VLC Player 的下拉菜单中手动选择 HDMI 输出时，它可以正常工作，但每次启动播放器时，我都必须手动将其设置为 HDMI 输出，不仅如此，如果我在播放列表中排队多个视频并选择 HDMI 输出，第一个视频可以正常播放，但一旦下一个视频开始，音频就会切换回耳机输出。这非常令人沮丧。
所以每次我想看一集时，我都必须手动将音频输出设置为 HDMI。
我尝试调整设置，但没有成功，也许我设置错了，然后它默认为耳机插孔或类似的东西。
这是我最近使用的设置：
我尝试过 HDMI 0 和 HDMI 1，但没有成功。
运行时modetest -c我得到以下输出：

它以不同的方式引用 HDMI 输出，我假设HDMI-A-1映射到vc4-HDMI-0VLC 播放器，并HDMI-A-2映射到vc4-HDMI-1VLC 播放器。
我究竟做错了什么？
答案1
因此，我上面的设置将默认输出设置为 ALSA 音频输出。
完成后，我需要从音频输出设置中选择 ALSA，而不是默认的“自动”设置。
这解决了这个问题。
