我对 MPD/MPC 越来越着迷。我正在尝试基本用途，播放网络播放列表。我的问题是当我试图停止它然后重新开始玩时。
加载中：
pi@raspberrypi:~ $ sudo mpd
pi@raspberrypi:~ $ cat /var/lib/mpd/state
sw_volume: 100
audio_device_state:1:My ALSA Device

[playing] #1/3 0:00/0:00 (0%)
volume:100% repeat: off random: off single: off consume: off
停止和清除：
pi@raspberrypi:~ $ mpc stop
volume:100% repeat: off random: off single: off consume: off
pi@raspberrypi:~ $ mpc clear
volume:100% repeat: off random: off single: off consume: off
我可以看到这不会立即改变。需要一些时间才能清除（并且仍然显示“state:play”）：
pi@raspberrypi:~ $ cat /var/lib/mpd/state
sw_volume: 100
audio_device_state:1:My ALSA Device
state: play
current: 1
time: 103.685000

几分钟后，我的状态文件已清除，但我无法再次播放：
pi@raspberrypi:~ $ cat /var/lib/mpd/state
sw_volume: 100
audio_device_state:1:My ALSA Device
state: stop
random: 0
repeat: 0
single: 0
consume: 0
crossfade: 0
mixrampdb: 0.000000
mixrampdelay: -1.000000
playlist_begin
playlist_end
pi@raspberrypi:~ $ mpc load http://www.wefunkradio.com/play/radio.pls
loading: http://www.wefunkradio.com/play/radio.pls
error: Timeout
一切都开始失败：
pi@raspberrypi:~ $ mpc
error: Timeout
pi@raspberrypi:~ $ mpc stop
error: Timeout
我发现它可以杀死 -9 mpd 的唯一解决方案，并且有时仍然有效，而其他一些则无效。我试图找到一个能够重现错误的规则，但我不能。
有什么建议吗？范围是：
- 加载网络播放列表
- 播放
- 停下来
- 清除播放列表
- 再次加载
- 再播一次
提前致谢
更新 在杀死MPD、重新启动MPD、加载播放列表和播放之间等待了很长时间，现在可以了。与时间有关吗？
