mpd - 脉冲和/或 alsa 问题

我在做什么？

我正在尝试首次让 mpd 工作，以便可以在多个 Linux 设备上传输音频。我的 mpd.conf 文件显示：

music_directory     "/home/john-mcbride/.mpd/music"
playlist_directory      "/home/john-mcbride/.mpd/playlists"
db_file             "/home/john-mcbride/.mpd/tag_cache"
log_file            "/home/john-mcbride/.mpd/mpd.log"
pid_file            "/home/john-mcbride/.mpd/mpd.pid"
state_file          "/home/john-mcbride/.mpd/state"
sticker_file                   "/home/john-mcbride/.mpd/sticker.sql"
user                "john-mcbride"
bind_to_address     "any"
input {
        plugin "curl"
}
audio_output {
    type        "alsa"
    name        "My ALSA Device"
}
audio_output {
    type        "pulse"
    name        "My Pulse Output"
    server      "localhost"     # optional
}

出了什么问题？

当我运行 ncmpcpp 时，曲目停留在暂停状态。以下是来自 mpd.log 文件的详细信息：

Jul 30 19:49 : player: problems opening audio device while playing "Music/Electro/Aphex Twin/AFX/1994 - Analogue Bubblebath (CD EP)/04 A F X 2.mp3"
Jul 30 19:51 : state_file: failed to create /home/john-mcbride/.mpd/state: Permission denied
Jul 30 19:51 : player: played "Music/Electro/Aphex Twin/AFX/1994 - Analogue Bubblebath (CD EP)/04 A F X 2.mp3"
Jul 30 19:51 : avahi: Service 'Music Player' successfully established.
Jul 30 19:51 : alsa_mixer: Failed to read mixer for 'My ALSA Device': no such mixer control: PCM

当我注释掉 ALSA 行时，我也收到 Pulse 错误：

Jul 30 19:49 : pulse_output: Failed to open "My Pulse Output" [pulse]: failed to connect: Connection refused

这些是我遇到的一系列问题中的最新一个。每次我以为已经修复了某个问题时，都会出现不同的错误。目前，它似乎是 ALSA、Pulse 和 mpd 权限的混合体。

问题！

那么，您能建议我应该怎么做才能使用 mpd 播放音乐吗？您能指出我这样做有什么根本问题吗（考虑到我希望能够在多个设备上访问它）？
