# -*- coding: utf-8 -*- """修「手表推了 mp3 过去，暂停不了」。 根因：play_audio 用 Windows MCI 直接播放文件，而 MCI **不是系统媒体会话**， 不响应全局多媒体按键（VK_MEDIA_PLAY_PAUSE）。手表发的「播放/暂停」正是 模拟媒体键，所以对推进去的音频完全无效 —— 只能靠「停止」（它会 close）。 修法：只要电脑正在播手表推的音频，媒体命令就直接作用于 MCI； 音量类仍然走系统媒体键（音量是全局的）。 另外补三条精确命令：audio_pause / audio_resume / audio_status。 """ from __future__ import annotations import sys from pathlib import Path ROOT = Path(r"C:\Users\shu\Desktop\deepseekagent\LanRemote\windows" r"\lanremote") ACTIONS = ROOT / "actions.py" SERVER = ROOT / "server.py" PROTOCOL = ROOT / "protocol.py" #
