为什么有些文件显示为灰色/无法播放？

当浏览库或尝试播放文件时，如果文件在数据库中，MediaMonkey 将以灰色显示文件，但无法播放，因为：

  1. 文件无法访问。
  2. 它们的格式不受支持

如果音轨没有显示为灰色但未播放或播放不正确，则可能是与输出相关的问题（与均衡器、DSP、音量调节或输出插件有关），该问题在“ 没有播放声音/声音损坏”中进行了讨论。

文件无法访问

无法访问的文件也将出现在“死链接”节点中（例如（如整个库 > 要编辑的文件 > 死链接节点），可以在其中修复它们。在以下情况下，文件将变得无法访问：

  1. 已使用 MediaMonkey 以外的工具移动文件，并且文件夹监控未配置为自动更新库以反映此类更改。
    • 如果您使用的是 MediaMonkey Gold，请选中所有灰色的曲目，然后依次点击“文件”>“查找已移动/丢失的曲目”。这将根据文件大小和时间戳，或曲目元数据，找到匹配的曲目。
    • 如果您没有 MediaMonkey Gold，请删除旧条目，并扫描曲目已移动到的位置。
    • 配置文件夹监控以防止这种情况再次发生。
  2. 包含媒体文件的驱动器已更改，新驱动器的驱动器 ID 与旧驱动器不同。要更正此问题，请先备份数据库，然后尝试以下操作之一：
    • 在 MediaMonkey 5+ 中，您可以右键单击驱动器（收藏夹名称（例如音乐）> 位置 > 驱动器号（例如 D:）），从上下文菜单中选择“媒体属性”以将驱动器指向正确的位置。
    • 如果您使用的是 MediaMonkey Gold，请选中所有灰色的曲目，然后依次点击“文件”>“查找已移动/丢失的曲目”。这将根据文件大小和时间戳，或曲目元数据，找到匹配的曲目。
    • 在 MediaMonkey 4 中使用第三方数据库插件中的文件更新位置。
  3. 文件存储在未连接的可移动驱动器上或无法访问的网络位置上。请通过连接驱动器或网络位置来解决。
  4. 文件存储到 MediaMonkey 没有权限的网络驱动器/映射驱动器。例如，如果驱动器使用一组凭据进行映射，但 MediaMonkey 在另一组凭据下运行。通过授予 MediaMonkey 访问该位置的权限来解决。
  5. 网络路径会映射到驱动器号（例如 J:）。在某些情况下，Windows 会更改 MediaMonkey 用来查找驱动器的驱动器 ID（而不是驱动器号）。解决方案是使用 UNC 路径而不是映射驱动器来访问文件：
    \ip _address\path（始终有效）
    \computer_name\path（通常有效）
    在 MediaMonkey 5+ 中，您可以右键单击“集合”>“位置”节点中的驱动器，然后使用上下文菜单中的“媒体属性”将驱动器指向正确的驱动器。
  6. 文件位于驱动器 A 或 B 上，MediaMonkey 无法访问它们。要解决此问题，请从MediaMonkey.ini中的 IgnoreDriveLetters=AB 中删除驱动器号（这只会影响安装了 MediaMonkey 4.1 之前的任何版本的 MediaMonkey 的用户）。

文件的格式不受支持

MediaMonkey 支持大多数常见的音频格式，但如果出现以下情况，可能不支持音频格式：

  1. 由于使用的 Windows 版本是 Windows N 版本，不包含多媒体组件，因此无法播放任何音频格式。可以通过安装缺少的编解码器来纠正此问题。
  2. 这可能是由于音频插件不兼容、DRM（数字版权管理）或缺少所需的编解码器而发生的。请参阅：

Why are some files Greyed Out / Fail to Play?

When browsing the Library or trying to play files MediaMonkey will display files in grey if they’re in the database, but not playable either because:

  1. The files are inaccessible.
  2. They’re in an unsupported format

If tracks don’t appear grey but aren’t playing or are playing incorrectly, it’s likely an output-related problem (related to the equalizer, DSPs, volume leveling, or the Output plug-in), an issue discussed at: “No Sound is playing / Sound is corrupted“.

Files are Inaccessible

Inaccessible files will also appear in the ‘Dead Links’ nodes (e.g. (like Entire Library > Files to Edit > Dead Links node) where they can be fixed. Files can become inaccessible if:

  1. Files have been moved using a tool other than MediaMonkey and Folder Monitoring isn’t configured to automatically update the library to reflect such changes.
    • If you have MediaMonkey Gold, select all the greyed out tracks and use File > Locate moved/missing tracks. This will find matching tracks based on file size AND timestamp, or track metadata.
    • If you don’t have MediaMonkey Gold, delete the old entries, and scan the location to which the tracks have been moved.
    • Configure Folder Monitoring to prevent this from recurring.
  2. The drive containing media files has been changed and the new drive has a driveID that differs from the old drive. To correct this, first back up your database and then try one of the following:
    • In MediaMonkey 5+ you can use right click on the drive (Collection Name (e.g. Music) > Location > Drive Letter (e.g. D:)) select ‘Media Properties’ from the Context Menu to point the drive to the correct location.
    • If you have MediaMonkey Gold, select all the greyed out tracks and use File > Locate moved/missing tracks. This will find matching tracks based on file size AND timestamp, or track metadata.
    • In MediaMonkey 4 use the third party Update Location of Files in Database Addon.
  3. Files are stored on a removable drive that is not connected or on a network location that is inaccessible. Resolve by connecting the drive or the network location.
  4. Files are stored to a networked drive/mapped drive to which MediaMonkey doesn’t have permissions. e.g. if the drive is mapped with one set of credentials, but MediaMonkey is running under a different set of credentials. Resolve by giving MediaMonkey permission to access the location.
  5. A network path is mapped to a drive letter (e.g. J:). In some cases Windows changes the driveID which is what MediaMonkey uses to find the drive (instead of drive letter). The solution is to access your files using the UNC Path instead of a mapped drive:
    \ip _address\path (always works)
    \computer_name\path (often works)
    In MediaMonkey 5+ you can use right click on the drive in the Collection’s > Location node and use Media Properties from the Context Menu to point the drive to the correct drive.
  6. Files are located on drive A or B and MediaMonkey isn’t able to access them. To fix this remove the drive letter from IgnoreDriveLetters=AB in MediaMonkey.ini (this only affects those who’ve installed any version of MediaMonkey prior to MediaMonkey 4.1).

Files are in an Unsupported Format

MediaMonkey supports most common audio formats, but audio formats may not be supported if:

  1. No audio formats can be played because the version of Windows used is Windows Windows N version, which doesn’t include multimedia components. This can be corrected by installing the missing codecs.
  2. It can occur because of audio plugin incompatibilities, DRM (digital rights management) or because required codecs are missing. See:

    CDs fail to play
