    由于需要做音频开发，使用linux真机，但是发现deepin 20.5 音频命令各种不行。各种尝试没发现解决办法。也查看了alsa 和 pulse 相关的配置和自启动参数，没看出啥问题。

    总之运行 paxxx 相关的命令 pactl paplay pacat parec ... 均是类似的报错，参考 env 也没看出啥，目前看到的是 PULSE_SERVER=tcp:fd70:73fc:5fb5::1 是 ip6 的 但是也没头绪。原本 aplay -D default 还能播放wav，一顿操作后，又是重装 又是各种重启 pulse配置更新尝试。好嘛，现在啥也不行了.

    paplay ~/Desktop/test.wav
    连接失败：拒绝连接

    aplay -D default ~/Desktop/test.wav
    ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
    aplay: main:830: audio open error: 没有那个文件或目录

    aplay -D pulse ~/Desktop/test.wav
    ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: 拒绝连接

    aplay: main:830: audio open error: 拒绝连接

    权限问题？

    linux的音频感觉是个坑，同样的代码，deepin、乌班图、debian都报这玩意（但音频能放出来）,windown10倒是啥报错没有

    胡翔宇：

    有可能，但是看启动脚本也没什么特别的。也有怀疑过是不是appampr安全防御的问题。

    想手动起pulseaudio 后台进程，但是杀了总自启。总的来说还没有确定的解决方式和根本原因定位。

    日志报错不代表不能用，linux会把你可能需要知道的信息告诉你，win一般连你需要知道的信息都不告诉你。个人觉得不是linux的坑的问题。

    胡翔宇：

    权限问题？

    sudo paplay /home/xxx/Desktop/test.wav
    请输入密码:
    验证成功
    连接失败：拒绝连接
    pa_context_connect() 失败：拒绝连接

    单纯权限问题，理论上这样能排除。但是这个更像是 pulse 的 server 和 client 通讯又问题，就是比较怀疑 ipv6??

    ========================

    问题是 为解决这个问题更新 了音频相关导致。要么没声音要么代码没法跑。。
