我想要通过多个输出通道来路由 PulseAudio。

我希望能够通过 3 个配置文件路由音频

output:hdmi-stereo+input:analog-stereo 在卡 0
output:analog-stereo在卡片 1 中

目前只有这个能产生声音
aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Right.wav
我需要它路由到hw:0,0，hw:0,3＆hw:1,0
我如何将其重新路由至所有三个？
如果有任何我可以查看的文档那就太好了。
更新
我尝试了以下步骤
pactl set-card-profile 0 output:hdmi-stereo
pactl set-default-sink alsa_output.pci-0000_00_0e.0.hdmi-stereo
现在我播放两个文件时都能听到声音
aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Right.wav
aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Right.wav
所以我尝试将两个水槽合并起来
pactl load-module module-alsa-sink device=hw:0,0 sink_name=analog
pactl load-module module-alsa-sink device=hw:0,3 sink_name=hdmi
pactl load-module module-combine-sink sink_name=combined slaves=analog,hdmi
pactl set-default-sink combined
然后我运行了以下命令
paplay --device=combined /usr/share/sounds/alsa/Front_Left.wav
我第一次运行它时，它在两个设备上都播放音频。但从第二次开始，它只在接收器上hw:0,0播放analog。
我认为不同的配置文件具有不同的优先级，不知道这是否会对输出产生影响。我不确定我需要查看哪些来源才能了解此行为。
