更改pulseaudio中的默认音频端口

Question

你好，经过几个小时的谷歌搜索后，我一片空白。

我已在 18.04 中成功配置音频，但需要帮助来更改端口设备的优先级。演讲者应优先！目前情况如下：

"$ pactl list sinks
Sink #0
    State: RUNNING
    Name: alsa_output.pci-0000_00_1f.3.analog-stereo
    Description: Built-in Audio Analogue Stereo
    Driver: module-alsa-card.c
    Sample Specification: s16le 2ch 44100Hz
    Channel Map: front-left,front-right
    Owner Module: 8
    Mute: no
    Volume: front-left: 35388 /  54% / -16.06 dB,   front-right: 35388 /  54% / -16.06 dB
            balance 0.00
    Base Volume: 65536 / 100% / 0.00 dB
    Monitor Source: alsa_output.pci-0000_00_1f.3.analog-stereo.monitor
    Latency: 39638 usec, configured 40000 usec
    Flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY 
    Properties:
        alsa.resolution_bits = "16"
        device.api = "alsa"
        device.class = "sound"
        alsa.class = "generic"
        alsa.subclass = "generic-mix"
        alsa.name = "ALC299 Analog"
        alsa.id = "ALC299 Analog"
        alsa.subdevice = "0"
        alsa.subdevice_name = "subdevice #0"
        alsa.device = "0"
        alsa.card = "0"
        alsa.card_name = "HDA Intel PCH"
        alsa.long_card_name = "HDA Intel PCH at 0x404a100000 irq 142"
        alsa.driver_name = "snd_hda_intel"
        device.bus_path = "pci-0000:00:1f.3"
        sysfs.path = "/devices/pci0000:00/0000:00:1f.3/sound/card0"
        device.bus = "pci"
        device.vendor.id = "8086"
        device.vendor.name = "Intel Corporation"
        device.product.id = "a348"
        device.form_factor = "internal"
        device.string = "front:0"
        device.buffering.buffer_size = "65536"
        device.buffering.fragment_size = "32768"
        device.access_mode = "mmap+timer"
        device.profile.name = "analog-stereo"
        device.profile.description = "Analogue Stereo"
        device.description = "Built-in Audio Analogue Stereo"
        alsa.mixer_name = "Realtek ALC299"
        alsa.components = "HDA:10ec0299,10251243,00100002"
        module-udev-detect.discovered = "1"
        device.icon_name = "audio-card-pci"
    Ports:
        analog-output-speaker: Speakers (priority: 10000, not available)
        analog-output-headphones: Headphones (priority: 9000, available)
    Active Port: analog-output-speaker
    Formats:
        pcm
"

耳机输出工作正常，但插孔检测有问题（我假设 ubuntu 认为有一个已插入）

那么问题来了：有没有办法改变 18.04 中的pulseaudio输出模式的优先级和/或修复插孔检测？

每次启动时，它都让我疯狂地改变输出端口（与 Windows 10 双重启动 - 单独的分区）

Answer 1

通过手动更改 GUI，您可以安装脉冲音频音量控制

sudo apt install pavucontrol

打开应用程序并选择要设置的音频流。

要在启动时设置某个输出，可以将代码写入启动项或~/.bashrc或~/.profile中，甚至注册一些在输出之间切换的快捷方式也很有用。

设置快捷键Settings > Keyboard > Shortcuts > Custom Shortcuts Alt+ L.

 pactl set-sink-port 0 analog-output-speaker

设置Alt+H

pactl set-sink-port 0 analog-output-headphones

您还可以将扬声器的优先级设置为高于耳机。
