我刚刚在配备 Celeron N3350 的迷你 PC 上安装了 Debian 12。目标是将其用于蓝光播放。到目前为止，视频很流畅，但我只能从插孔模拟输出获取音频。

所以我尝试了
>aplay -D plughw:0,0 ~/Wav_868kb.wav
Playing WAVE '/home/roberto/Wav_868kb.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
它在模拟插孔输出上发出声音。
使用与 5、6、7 相同的命令， aplay -D plughw:0,5 ~/Wav_868kb.wav我从通过 HDMI 连接的投影仪（支持音频）中听不到任何声音（它在使用 Windows 10 的设备上播放声音）。
我检查过，尽管有正确的设备alsa-mixer，但我无法清楚地识别任何“HDMI”/proc/asound/devices

我在这里做错了什么？需要修复/验证什么才能输出 HDMI 声音？
在内核级别，我没有看到重大问题，如下所示，但也许我错了。
