Archlinux 配置 LDAC 连接蓝牙耳机

Contents [hide]

1 安装音频与蓝牙依赖
2 安装 libldac
3 安装 pulseaudio-modules-bt
4 查看蓝牙设备连接方式
5 使用 bluetoothctl 调试

安装音频与蓝牙依赖

sudo pacman -S pulseaudio-alsa bluez-utils

安装 libldac

从 AUR 中获取 libldac

mkdir -p ~/Software/AUR
cd ~/Software/AUR
git clone https://aur.archlinux.org/libldac.git
cd libldac
makepkg -si

安装 pulseaudio-modules-bt

标准 pulseaudio-bluetooth 包中不含 libldac 支持，从 AUR 中获取 pulseaudio-modules-bt

mkdir -p ~/Software/AUR
cd ~/Software/AUR
git clone https://aur.archlinux.org/pulseaudio-modules-bt.git
cd pulseaudio-modules-bt
makepkg -si

查看蓝牙设备连接方式

pactl list | grep a2dp

出现 bluetooth.a2dp_codec = “LDAC” 则说明设置成功

使用 bluetoothctl 调试

重启后使用蓝牙管理器可直接配置蓝牙耳机，若出现问题，可使用 bluetoothctl 进行调试

bluetoothctl

启用蓝牙设备

[bluetooth]# power on
[bluetooth]# agent on
[bluetooth]# default-agent
[bluetooth]# scan on

出现类似信息则说明发现新设备

[NEW] Device 00:1D:43:6D:03:26 Lasmex LBT10

使用下列命令配对并连接

[bluetooth]# pair 00:1D:43:6D:03:26
[bluetooth]# connect 00:1D:43:6D:03:26
