I have been using an HDMI cable to connect our Chromebook CB3-431 to our Samsung TV for several years. Yesterday, the audio just stopped working on the Chromebook, but only when the HDMI cable is plugged into the TV. The sound comes out of the television, but it isn't very loud. The sound on the laptop works fine when the cable is not plugged into the TV. The visual signal is never affected. I suspected the problem was the cable, so I tried using a different HDMI cable, but the problem did not go away. So . . . I am guessing the issue might be in the laptop, but I am not sure. Thanks in advance for any ideas of what to try.
