Watching NOWTV through the stick on our sharp tv but the timing of the voice in all programs not just sports is a few seconds behind, why? How can this be fixed? Stick only purchased 3 months and was fine for the first 2 months.
First thing i would try is switch the power off to both your stick and television and temporarily disconnect the stick from the HDMI port or try a different HDMI port on the TV.
Sometimes a reboot on both your playback device and Router will resolve picture and sound issues.
Another thing you could try is go into the stick menu settings and under Audio play around with the different sound options (start with Audio Mode set at Stereo and HDMI set to PCM Stereo) to see if any settings makes any improvement.
Also check in your television settings under sound if there is an Audio Sync delay option.
