My laptop has an HDMI out port and my new TV has HDMI in ports. Hooking them up so that I can use the laptop to play movies with sound on the TV works fine. However, I haven’t been able to find a way to send out just video without sound. Sometimes I want to keep the audio coming through my laptop speakers so I can put headphones on and not have everyone around me tell me to turn the sound down… is there a way to do that?
You haven’t said which operating system you’re using, but on Windows I believe you can just change the default playback device in via the Sound control panel applet. It will probably change to HDMI automatically when you plug the cable in, but then you should be able to just go into control panel and switch it back to your laptop.
Alternatively, your media player may have options for which device to use for sound.
