有問題，聊聊看

Primuse 会按专辑名和专辑艺术家组合整理资料库，未提供专辑艺术家时再回退到曲目艺术家；分组身份不带音乐源 ID。因此多个源里的同一专辑可能合并，合辑标签不同也可能拆开，不能把全部资料库的数量直接等同于单台服务器。排查时先比较同一来源、同一范围，再检查专辑艺术家标签。

先查看歌曲标签里的曲号。Primuse 会读取 UPnP 服务器提供的有效曲号；服务器未提供时，反复扫描通常无法补齐。当前该来源还未读取分碟号，多碟专辑可能无法按原分碟顺序排列。请核对服务器提供的信息；特定 NAS 或 ATRAC 文件的情况，还需结合设备返回的数据确认。

Yes. With iCloud Sync on, watch progress, collections, favorites, media sources and playback settings sync across devices using the same iCloud account. Progress sync with Jellyfin, Emby or Plex servers is not guaranteed in the current version.

不需要先在手机上手动打开 Primuse：在车机上点 Primuse，iOS（iPhone 的操作系统）可以直接启动手机里的 App，并显示 CarPlay 界面，手机端页面无需打开。

但这不等于“只要连上车机，Primuse 就一定自动启用”。对于手机和车机都不操作、仅连接 CarPlay 的情况，目前不能保证每次都会自动启动，也不能仅凭未自动启动就认定是 Primuse 的故障。

Yes. MKV, MP4, TS and similar files play through the Viozi Engine by default, using the system decoders. Files it can't play fall back automatically. Some codecs may still not play on some devices.

The Viozi Engine passes Atmos to the system's native path, but whether it is actually output depends on the device, the connection and whether your TV, receiver or headphones support it. Reading an Atmos track does not guarantee Atmos output; check the format shown on the receiving device.

Yes. The package cannot exceed 8 MB, and each device has a limited number of uploads per day (currently 5 by default). When they are used up, wait until the time the app shows. If the package is too large, turn off Logs and try again.

Uploads go to the author's server, are used only to troubleshoot, and are deleted after 30 days. The app shows this note before uploading, and only the reports, logs and text you select are uploaded.

In the App Store version, Diagnostic Reports has no Export Log. Logs can only be attached, in their most recent part, through Upload to the Author. TestFlight builds can export the full log. The Mac diagnostics window has Export Log.

支持 iPhone 和 iPad（iOS / iPadOS 18 及以上）、Mac（macOS 15 及以上）和 Apple TV（tvOS 18 及以上）。

iPhone / iPad：「设置」→ 最下方「关于」分组 →「诊断报告」。Mac：「设置」→「关于」→「诊断日志…」。Apple TV 没有这个入口。

先在媒体源菜单中运行「媒体源体检」。常见原因是不在同一局域网、VPN / 代理接管了内网地址、用户名或密码错误、或没有选择共享目录。离开家里网络时需要填写公网地址。
