ALSA snd_aloop 显示为“内部音频”

ALSA snd_aloop 显示为“内部音频”

我正在使用 ALSA 模块 snd_aloop,以便能够将我的 ALSA DJ 软件的输出广播到网络(即 facebook live、Zoom),我通过 modprobe 加载它。它运行得很好。我可以在这个环回和我的内置麦克风之间切换,效果很好。

但是我有一个恼人的问题:我的硬件声卡和虚拟环回声卡都显示为“内部音频立体声模拟”(在我的法国系统上为“Audio interne Stéréo Analogique”)。

它们在 ubuntu 声音首选项、pavucontrol 以及应用程序/浏览器音频选择器中共享相同的名称。

我想以不同的方式调用 snd_aloop 源和接收器,即“Loopback”,这样我就可以区分它们,而不是每次都进行反复试验。

我研究了有关 Alsa 和 Pulse 的非常有趣的详细文档,做了一些“pacmd update-source-proplist”,但无法设法更改 snd_aloop 的名称。

有人能帮助我吗?

非常感谢

为了澄清起见,这里是我的列表接收器输出:我希望最后一个 device.description =“Audio interne Stéréo analogique”显示一些不同的东西
