I just checked, and the audio output is off. I also tried a different HDMI cable and port on my TV and computer. Sigh, still no sound. I can use other means for sound such as my Bluetooth speaker, or my old computer speakers. But the TV speakers just don't seem to be working.
Oh, Oh! I got sound!!! When I first checked it the Zorin output device had changed, so I changed it back to HDMI and it worked! Wow!
Thank you so much. It looks like changing the HDMI port and cable worked!!
Thank you again!
