如何设置pulseaudio以使用2个配置文件中的数字和模拟端口？

我最近安装了 Debian 测试，并使用 Xfce 作为我的桌面环境。我使用的是主板内置的Realtek声卡。

在 Windows 上，或者当我尝试使用 GNOME 的 Debian 时，我能够轻松地在数字和模拟输出（S/PDIF 和耳机）之间切换，但是到目前为止，我只能通过使用pavucontrol.

这数字立体声 (IEC958) 输出配置文件仅显示一个端口：数字输出（S/PDIF）。 这模拟立体声输出配置文件显示两个端口：线路输出（未插入）和耳机（已插入）。

有没有一种方法可以将耳机和 S/PDIF 端口放在一个配置文件上，或者这就是pulseaudio 的工作方式？

答案1

对于其他人在寻找解决方案时发现这个问题，这对我有用。

打开/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf，并将其添加到其中：

[Profile output:analog-stereo+output:iec958-stereo+input:analog-stereo]
description = Digital Stereo (IEC958) Output + Analog Stereo Duplex
output-mappings = analog-stereo iec958-stereo
input-mappings = analog-stereo

这将创建一个包含模拟立体声输入+输出和数字立体声输出的配置文件。

要应用更改，请重新启动 PulseAudio 守护程序：

pulseaudio --kill
pulseaudio --start

现在您应该看到能够在 pavucontrol 中使用新的配置文件，并同时使用两个输出。
