基于KASMvnc的Obsidian Remote Docker容器音频播放失败（DBus错误）

我在用基于KASMvnc的Obsidian Remote Docker镜像时遇到问题：Obsidian能正常运行，但库内的MP4文件只能播放画面，没有声音输出。容器采用Pulseaudio处理音频，Docker主机的音频功能正常，推测问题和DBus相关。

配置信息 #

Dockerfile #

错误日志 #

播放带声音的MP4时，容器日志重复出现以下错误：

obsidian-remote | [961:0223/173013.413639:ERROR:bus.cc(399)] Failed to connect to the bus: Could not parse server address: Unknown address type (examples of valid types are "tcp" and on UNIX "unix")

求各位提供解决容器内音频播放问题的思路，谢谢！
