默认情况下raspbmc不是默认启用hdmi输出。连上hdmi显示器是总是提示无信号,将sd卡插入电脑中在config.txt加入下面的两个参数即可。
hdmi_force_hotplug=1
hdmi_drive=2
提示信息:
hdmi_force_hotplug=1 sets the Raspbmc to use HDMI mode even if no HDMI monitor is detected. hdmi_drive=2 sets the Raspbmc to normal HDMI mode (Sound will be sent if supported and enabled). Without this line, the Raspbmc would switch to DVI (with no audio) mode by default.
其实如果能远程登录Xbmc也可以在/boot目录下找到congfig.txt文件。
