如何让“模拟立体声”和“数字立体声 (HDMI)”同时显示在 PulseAudio 输出端口中？

正如标题所述，我无法在 PulseAudio 中看到内置选项Analog Stereo和Digital Stereo (HDMI)输出选项。我可以在“配置”选项卡中更改配置文件，并在 和 之间切换Analog Stereo Output，Digital Stereo (HDMI 5) Output并且声音输出按预期工作。但是，“输出设备”选项卡仅显示一个输出接收器或另一个，因此 PulseAudio 托盘插件不提供更改输出端口的选项。

我是否需要定义包含两个音频接收器的自定义 PulseAudio 配置文件？我在其他安装中没有看到这个问题，在其他安装中，连接时会自动出现新的输出端口。我Xubuntu 20.04.1 LTS在 LG Gram 17 上使用。

提前致谢！

答案1

由于模拟和各种 HDMI 接收器来自同一张卡，默认配置似乎将它们全部配置到一个配置文件中，这意味着一次只能使用一个配置文件。因此确实需要一个自定义配置文件来解决这个问题。

对于我的情况，我按照以下说明进行操作在pulseaudio中编写配置文件。我创建了2个文件：

/etc/udev/rules.d/91-pulseaudio-intel.rules

# Custom Profile for onboard Intel 8086:a171

SUBSYSTEM!="sound", GOTO="xpulseaudio_end"
ACTION!="change", GOTO="xpulseaudio_end"
KERNEL!="card*", GOTO="xpulseaudio_end"

SUBSYSTEMS=="pci", ATTRS{vendor}=="0x8086", ATTRS{device}=="0xa171", ENV{PULSE_PROFILE_SET}="intel-hdmi+analog.conf"

LABEL="xpulseaudio_end"

/usr/share/pulseaudio/alsa-mixer/profile-sets/intel-hdmi+analog.conf

[General]
; # Instead of defining all profiles manually, autogenerate
; # them by combining every input mapping with every output mapping
auto-profiles = yes

[Mapping analog-stereo]
device-strings = front:%f
channel-map = left,right
paths-output = analog-output-speaker analog-output-headphones
paths-input = analog-input-internal-mic analog-input-headset-mic
priority = 15

[Mapping hdmi-stereo]
description = Digital Stereo (HDMI)
device-strings = hdmi:%f
paths-output = hdmi-output-0
channel-map = left,right
priority = 9
direction = output

[Profile output:analog-stereo+output:hdmi-stereo+input:analog-stereo]
description = Analog Stereo + Digital Stereo (HDMI) + Analog Stereo Input
output-mappings = analog-stereo hdmi-stereo
input-mappings = analog-stereo

[Profile output:analog-stereo+output:hdmi-stereo]
description = Analog Stereo + Digital Stereo (HDMI)
output-mappings = analog-stereo hdmi-stereo

之后就是跑步的问题了

$ sudo udevadm trigger -ssound
$ pulseaudio -k

现在水槽是分开的。

我只需要模拟立体声和 HDMI-0 作为接收器，麦克风作为源。您提到了 HDMI-5，因此您可能想在路径输出中使用 hdmi-stereo-extra4。如果您还需要其他 HDMI 接收器，只需添加它们的映射，并且 - 如果您想要单独使用所有它们的选项 - 为每个“启用”接收器和源的组合提供一个配置文件。

Ubuntu 20.04 中的文件/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf（或脉冲音频 git 存储库) 有多种映射可供您复制。
