No Sound on TV when Laptop connected through HDMI, but is listed as Default Device


Oct 3, 2016
Yesterday I was watching netflix on my TV through my laptop, using the HDMI cable, it was working just fine. But this morning when I plugged it in, there is absolutely no sound. Both the TV and the laptop have sound individually when they are not connected, but when I connect the two, through the HDMI cable, the sound is muted on the laptop. Even when I manually change the sound, immediately when I click off of the slider, the laptop mutes itself again. The TV is listed as the default device, and as I said, it was working just fine earlier, so I have no idea why it won't work today! Please can someone help as I've been trying to fix this for over an hour and have got to that really angry, frustrated crying stage!!
