问题[ncmpcpp](ubuntu)

我的问题是这个。我一直在配置mpd和ncmpcpp。这是我的mpd配置：

music_directory "/media/dylan-roman/Acer/Users/Dylan/Music"
playlist_directory "/media/dylan-roman/Acer/Users/Dylan/Music"
db_file "/home/dylan-roman/.mpd/mpd.db"
log_file "/home/dylan-roman/.mpd/mpd.log"
pid_file "/home/dylan-roman/.mpd/mpd.pid"
state_file "/home/dylan-roman/.mpd/mpdstate"
user                "mpd"
bind_to_address     "localhost"
port "6600"

#audio_output {
#type "alsa"
#name "alsa for audio soundcard"
#mixer_type "software"
#}

audio_output {
type "pulse"
name "pulse audio"
}

audio_output {
type "fifo"
name "my_fifo"
path "/tmp/mpd.fifo"
format "44100:16:2"
}

这是我的 ncmpcpp 配置：

[mpd]
mpd_music_dir = "/media/dylan-roman/Acer/Users/Dylan/Music"
mpd_host = "localhost"
#mpd_port = "6600"
mpd_crossfade_time = "2"
ncmpcpp_directory = /home/dylan-roman/.ncmpcpp

[visualizer]
visualizer_fifo_path = "/tmp/mpd.fifo"
visualizer_in_stereo = "no"
visualizer_type = "wave"
visualizer_output_name = "my_fifo"
visualizer_look = "│┃"
visualizer_color = "default"

[header]
header_visibility = "no"
header_window_color = "default"
volume_color = "default"
state_line_color = "black"

[playlist]
playlist_display_mode = "classic"
song_list_format = "{{%a - %t}|{%f}}{$R%l}"
now_playing_prefix = "$b$2"
now_playing_suffix = "$/b$9"

[statusbar]
progressbar_look = "─╼ "
progressbar_color = "black"
statusbar_visibility = "no"
statusbar_color = "default"
song_status_format = "{{%a{ - %t}}|{ - %f}{ - %b{ (%y)}}}"

[library]
song_library_format = "{{%a - %t}|{%f}}{$R%l}"
empty_tag_color = "black"

[global]
colors_enabled = "yes"
main_window_color = "default"
centered_cursor = "yes"
enable_window_title = "yes"
external_editor = "vim"

一切似乎都正常，但是当我播放歌曲时，它没有声音，出现以下消息：

MPD: no mixer

我已经用谷歌搜索了解决方案，但我没有设法修复问题

这是我在运行 systemctl --user status mpd 时得到的：

`● mpd.service - Music Player Daemon
     Loaded: loaded (/usr/lib/systemd/user/mpd.service; enabled; vendor preset: enabled)

` 和执行 sudo systemctl status mpd 时的 this

我找不到将 ncmpcpp 中当前播放歌曲的标题复制到剪贴板的方法。

有什么捷径可以做到这一点吗？

Ubuntu 版本：19.10：

$ lsb_release -r
Release:    19.10

ncmpcpp 0.8.2：

$ ncmpcpp -v
ncmpcpp 0.8.2

optional screens compiled-in:
 - tag editor
 - tiny tag editor
 - outputs
 - visualizer
 - clock

encoding detection: enabled

我正在使用 Ubuntu 16.04。我刚刚安装了 mpd 和 ncmpcpp。每当我播放任何音频文件时，ncmpcpp 都会检测到该文件并说它正在播放，但没有播放实际的音频。我按照本教程安装和配置 mpc 和 ncmpcpp。这是我的mpd配置：

music_directory     "~/Music"
playlist_directory      "~/Playlists"
db_file         "~/.local/share/mpd/mpd.db"
log_file            "~/.local/share/mpd/mpd.log"
pid_file            "~/.local/share/mpd/mpd.pid"
state_file          "~/.local/share/mpd/mpd.state"
sticker_file            "~/.local/share/mpd/sticker.sql"

bind_to_address     "127.0.0.1"
log_level           "default"
restore_paused "yes"
metadata_to_use "artist,album,title,track,name,genre,date"
auto_update "yes"

input {
        plugin "curl"
}

audio_output {
    type        "pulse"
    name        "pulse audio"
}

audio_output {
    type        "fifo"
    name        "mpd_fifo"
    path        "/tmp/mpd.fifo"
    format      "44100:16:2"
}

编辑：我还想澄清一下，我试图安装最新版本，正如它在这个答案中所说的那样，但我收到了其中一个包的消息：

E: Package 'libsystemd-daemon-dev' has no installation candidate

所以，我下载了 .deb 文件并尝试从那里安装它。当我运行“sudo dpkg -i”和文件路径时，我收到此错误：

dpkg: error processing package libsystemd-daemon-dev (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 libsystemd-daemon-dev

当我在 ncmpcpp 中播放音乐时，youtube 视频不起作用（反之亦然）

我一次只能玩一个，这是为什么呢？我如何解决它？

在 macOS 上，我可以同时播放 ncmpcpp 和 youtube 视频，现在我很好奇为什么。

（一周后更新：对于将来发现此问题的任何人，我决定使用 cmus + cava 作为解决方法，因为 cmus 可以与其他所有内容一起使用。）

三周后更新： cmus + vis 工作正常，你只需要用脉冲编译 cli-visualizer。https://github.com/dpayne/cli-visualizer#pulse-audio-setup-easy

一个月后更新：我找到了解决方案，这里就是这个答案：https ://askubuntu.com/a/555484/913725

在视图1中，在ctrl+s（对所有歌曲进行排序）之后，歌曲被排序但也被复制。之后的额外排序不会进一步重复它们。

我怎样才能防止这种重复？是什么导致了这种行为？
