ubuntu 20.04下没有声音

[li-fang]

感谢分享！目前使用良好，除了语音消息没声音，视频也没有声音。AUDIO_ID已经改成本地查到的，是否是因为dockerfile里面的AUDIO_ID也需要改呢

俺也一样

希望对别人有帮助， 在20.04, 22.04下测试后都有声音

初次启用使用脚本:

rm -rf /tmp/pulseaudio.socket
rm -rf /tmp/pulseaudio.client.conf
pactl load-module module-native-protocol-unix socket=/tmp/pulseaudio.socket
cat <<EOT >> /tmp/pulseaudio.client.conf
default-server = unix:/tmp/pulseaudio.socket
# Prevent a server running in the container
autospawn = no
daemon-binary = /bin/true
# Prevent the use of shared memory
enable-shm = false
EOT
xhost +
docker run -d --device /dev/snd --ipc=host \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -v $HOME/WeChatFiles:/WeChatFiles \
    -v /tmp/pulseaudio.socket:/tmp/pulseaudio.socket \
    -v /tmp/pulseaudio.client.conf:/etc/pulse/client.conf \
    -e DISPLAY=unix$DISPLAY \
    -e XMODIFIERS=@im=fcitx \
    -e QT_IM_MODULE=fcitx \
    -e GTK_IM_MODULE=fcitx \
    -e PULSE_SERVER=unix:/tmp/pulseaudio.socket \
    -e PULSE_COOKIE=/tmp/pulseaudio.cookie \
    -e AUDIO_GID=`getent group audio | cut -d: -f3` \
    -e GID=`id -g` \
    -e UID=`id -u` \
    --name wechat \
    bestwu/wechat
xhost -

在container 创建之后不需要每次使用run，因为run = create + start. 如果使用run 每次都会创建一个新的container. 改使用脚本

rm -rf /tmp/pulseaudio.socket
rm -rf /tmp/pulseaudio.client.conf
pactl load-module module-native-protocol-unix socket=/tmp/pulseaudio.socket
cat <<EOT >> /tmp/pulseaudio.client.conf
default-server = unix:/tmp/pulseaudio.socket
# Prevent a server running in the container
autospawn = no
daemon-binary = /bin/true
# Prevent the use of shared memory
enable-shm = false
EOT
xhost +
docker stop wechat
docker start wechat
xhost -
