On startup, when a custom sound has been set for session completion and needs input, the sound effect is played by the Copilot App, but I also receive a notification from PowerShell that Copilot needs input, etc. Only Windows reads that message with TTS.

So essentially I'm enjoying Alan Rickman telling me he needs more info, but less so because I'm having to hear Windows TTS tell me as well.

在 Windows 上复现 /chat 路径的启动流程，使用自定义的会话完成声音以及一个需要输入的会话。检查 Copilot App 声音和 PowerShell 通知是如何触发的。完成标准是自定义声音仍会播放，同时 Windows TTS 不会重复播报消息。
