2023-01-01 13:10:09.794 291-949 AudioPolicyManager pid-291 E unknown stream type 13

这看起来像是一个 Android 系统中的错误日志，其中 AudioPolicyManager 试图处理一个未知类型的音频流（stream type 13）。这可能是由于应用程序或系统中的某个组件配置不正确或存在故障所致。建议您检查设备上最近安装的应用程序或更新，并尝试卸载或回滚以查看问题是否得到解决。如果问题仍然存在，可能需要在设备上进行故障排除或考虑联系设备制造商或技术支持。

引用\[3\]:ubuntu 10.0开启配置nfs 服务service nfs start时出现: Failed to start nfs.service: Unit nfs.service not found. 原因是ubuntu 10.0以上的版本取消了service nfs start。 改成了sudo service nfs-server start 。这样就完成启动了。 在执行sudo service nfs-server status就可以看到 Loaded: loaded (/lib/systemd/system/nfs-server.service; enabled; vendor prese Active: active (exited) since 六 2016-07-09 06:58:33 CST; 4h 22min ago Process: 866 ExecStart=/usr/sbin/rpc.nfsd $RPCNFSDARGS (code=exited, status=0/ Process: 863 ExecStartPre=/usr/sbin/exportfs -r (code=exited, status=0/SUCCESS Main PID: 866 (code=exited, status=0/SUCCESS) CGroup: /system.slice/nfs-server.service 。
问题:Failed to start nfs-server.service: Unit nfs-server.service is masked.
回答: 当出现"Failed to start nfs-server.service: Unit nfs-server.service is masked"错误时，这意味着nfs-server服务被屏蔽了。这可能是由于系统配置或管理员设置的原因。要解决这个问题，可以尝试使用以下命令来解除屏蔽并启动nfs-server服务:
sudo systemctl unmask nfs-server.service
sudo systemctl start nfs-server.service
这样就可以解除屏蔽并启动nfs-server服务了。如果仍然遇到问题，建议检查系统配置和管理员设置，以确定是否有其他原因导致nfs-server服务无法启动。

这是一个 Kubernetes API Server 启动失败的错误信息。可以看到，该服务的状态为“failed”，原因是“start-limit”。在这种情况下，通常是由于服务启动失败多次而被 systemd 限制了启动次数。可能需要查看 kube-apiserver 的日志文件来获取更多信息，以确定导致服务启动失败的根本原因。
