主要參考這里
關(guān)鍵參考這里

1. 確認聲卡名字

sudo apt install alsa-utils
aplay -l 查看聲卡名字

card 1: Generic [HD-Audio Generic], device 0: ALC287 Analog [ALC287 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

聲卡名字是 Generic

2. 起一個容器

docker pull ubuntu:20.04

docker run -it --privileged --device /dev/snd --env ALSA_CARD=Generic --name test 33985b2ba010 /bin/bash

# docker stop test && docker rm test

apt update
apt install vim alsa-utils

3. 配置文件

vim /etc/asound.conf

pcm.!default{
    type hw
    card 1
    device 0
} 
ctl.!default{
        type hw
        card 1
        device 0
}
timer.!default{
        type hw
        card 1
        device 0
}

4. 安裝播放器，測試音頻

apt install sox libsox-fmt-all
play xxx.mp3
