Pulseaudio HDMI 接收器更改名称

Pulseaudio HDMI 接收器更改名称

我正在处理一个pulseaudio我无法弄清楚的小不便。我有一台运行 Arch Linux 的 ThinkPadT460s 以及一个扩展坞。连接到该底座的是屏幕和我的电视通过接收器。

的输出xrandr

现在,如果我连接电视,我还想将声音切换到 HDMI。在一个在屏幕配置之间切换的脚本中,我还添加了一行来更改声音, fe 切换回我拥有的内部声音 pactl set-card-profile 0 output:analog-stereo

然而,电视(这里是DP2-1)似乎在pulseaudio中切换了ID。有时我需要使用pactl set-card-profile 0 output:hdmi-stereo-extra1(内部称为 HDMI 2),有时pactl set-card-profile 0 output:hdmi-stereo-extra3(内部称为 HDMI 4),但我还没有真正弄清楚原因。我也看不到任何具体的触发器,有时在重新启动配置文件名称开关后。

有谁知道要测试什么来弄清楚这里发生了什么?

答案1

在尝试了一些事情之后,我可以给出一个不满意但有效的答案。

pactl list cards当我的电视打开时,仔细查看输出,该条目显示了实际的设备名称:

[...]
                hdmi-output-3: HDMI / DisplayPort 4 (priority: 5600, latency offset: 0 usec, available)
                        Eigenschaften:
                                device.icon_name = "video-display"
                                device.product.name = "VSX-330"
                        Teil der/des Profil(s): output:hdmi-stereo-extra3, output:hdmi-stereo-extra3+input:analog-stereo, output:hdmi-surround-extra3, output:hdmi-surround-extra3+input:analog-stereo, output:hdmi-surround71-extra3, output:hdmi-surround71-extra3+input:analog-stereo
[...]

由于我正在寻找简单的立体配置文件,因此我可以使用以下命令获取此特定条目

pactl set-card-profile 0 $(pactl list cards | grep -A1 'VSX-330' | awk '{print substr($4, 1, length($4)-1)}' | tail -1)

这不太漂亮,但到目前为止似乎已经成功了。这似乎与我的屏幕在对接设备时注册pulseaudio 的速度不是特别快有关。

希望这可以解决问题并帮助其他有类似问题的人!
